Quarians vs the rest on geth a.k.a. "this fandom keeps giving me Kepral's Syndrome"

Why do people believe that the quarians are, as compared to the other races, somehow exceptionally negative towards the geth?

The sad truth for the latter is that no one wants them. For all practical purposes, there's a scientific consensus in the galaxy that artificial intelligence capable of infiltrating the Extranet is a deadly threat to all developed organic life and research on creating it is considered a crime against the entire galaxy.[1] It is not a dead letter: when the Council discovered in 2165 that Alliance was doing research on artificial intelligence of unknown origin, it's been decided that humanity is stripped of all military independence, for punishment and prevention of repeating the issue[2]; they backed down with a dose of hesitation after the human Ambassador threatened them with armed resistance should they actually impose those sanctions.[3] Even tinkering with geth technology is prosecuted with the same rigour.[4] The reaction of the Council races* to the Rannoch uprising wasn't "oh, how nice, we have new synthetic friends" but a siege of an entire sector of the galaxy in preparation for a defensive war.[1] Even though this politics is just what science determined as the only way of preserving organic life in the long run, the creator of the Codex, Legion and EDI didn't hesitate to call it "pure racism".[5] Shepard can say a few bitter words to Tali in ME1 but if anyone is to be representative to the galaxy's opinion, it's raised in its heart Garrus, who reproaches the quarian in an elevator that her grandfathers brought a danger upon the rest.[6] Humans aren't lenient, either.[7] Just because they let the geth free, the quarians are treated worse than a race that tried to slaughter the entire galaxy at its time (the krogans) – when they once found a planet they could settle on, the Council chased them away with mass destruction weapons use threat and gave it to the biologically unfit** to it elcor instead[8]. After the known party at the Citadel, all armies of the galaxy remodeled their weapons against enemies such as geth, which means that the negative sentiment grew even further; indeed, you can see it from the turian from the hackers circle in Andromeda or from the "strengthened" security at the Citadel in ME2.
Javik's motto is "the only good synthetic is a dead synthetic"; after Legion is acquired in ME2, Jacob and Miranda discuss whether he's to be shot, thrown out an airlock or sold to Cerberus; Wrex's comment after Feros is that it was his kind of mission because he "killed a buch of synthetics and ended with a big boom". If Tali said anything so edgy except the circumstances of her father's death, the squawk and butthurt in the fandom would be insufferable.
In conclusion, except one optional dialogue, there was no sign of sympathy towards the geth from non-quarians between the destruction of the Council's diplomatic vessels and Shepard and Legion shaking their hands.

Now quarians. They're usually looked on through the lens of Admiral Gerrel, which of course closes the matter, but is as intellectually honest as equating all the geth with the heretics.
We already know that the attempt to shut the geth down on Rannoch was just a realization of a law based on science, everyone else would do the same, sooner (proof: no one before the quarians or after them came so far at creating artificial intelligence) and probably, not being as much emotionally bound to AI, without obstructions in the form of people shielding their synthetic children with own bodies. We know from history that when the turians found themselves in a similar situation as the quarians around the Trilogy's time (i.e. a threat to the biological existence[9]), they didn't hesitate to bring near extinction to another species. It's naive to think that humans, salarians or anyone except the rachni would not try to take their homeworld back from machines if their existence depended on it.
It's not exactly clear what it refers to, but it's said that quarians universally believe themselves to be giulty of hubris for their actions on Rannoch.[10] Rael'Zorah can be considered the greatest war criminal for pursuing experiments on the geth. Many quarians during the time of exile attempted to contact the geth and make friends with them***; some of them even managed to return alive.[11] Despite the low chances because of the Council and its fleet, the anti-war pro-colonization party of Ysin'Mal and Zaal'Koris was growing in strength, which resulted in a landslide of the pro-peace side in the Admiralty until Xen and Raan opted for war, and Idenna's mission. It couldn't happen without some basis in society, like the Nedas movement****. Finally, the only way to reconcile ME3's SP and MP modes plot-wise it to make peace between the quarians and the geth, which means that it's semi-canon***** that even that Han'Gerrel who ordered to shoot at a ship Tali and Shepard were on, held fire to the geth in the critical moment.

Concluding, despite that the quarians enter active conflict with the geth, it's not caused by some phobia, but necessity. Situation aside, it's the quarians who sympathize with the geth most and only among the quarians there are cases of pursuit of coexistence with the geth. So, the question from the first paragraph returns: why are people so wrong? Is this ignorance? Conformism to Mac Walters' narration? Disdain for talifans? Discuss.

* note that the source doesn't mention any hostile reaction of the Terminus systems to the presence of Council fleets, which probably means that they didn't mind it in this specific case
** assuming it had dextro life, which is a precondition for long-term quarian colonization
*** now remember Alliance's warnings in geth planet descriptions in ME2
**** "nowhere", quarian hippies who tattoo "forget Rannoch" on themselves, described in ME: Annihilation
***** defined as "belonging to the intersection of all possible Trilogy playthroughs that don't end prematurely (i.e. by dying in the SM) and sustain world consistency wherever possible" (most people would call it simply "canon")
