Can we be racist? [in Andromeda]

Based on the info we have about the dialogue choices so far, I'm guessing any racism will be a mix of consistent dialogue choices and headcanon. 

For example: 
You could go out of your way to make sure that when you are dealing with a specific race, they always get the short end of the stick. Kinda like Saren, he always got the job done, but if there was a way to do the job that caused the death of some humans, he'd do it that way. The game may not 'call you out' for these actions, but you're own RP could be Ryder is doing this cos she hates this race.

It might make sense for Alec Ryder to not like Turians, due to his background, his kids pick that racism up from him and now every time you interact with Turians Ryder is more of a dick & fucks up their colony on her way to complete whatever task she has there or just flat out doesn't help them when asked. 

You're RPing being a racist, and the Turians end up being affected negatively in game.
