Oh hey, I've got something for this that's prejudiced, but neither racist nor sexist.
Back when PAYDAY2 was still a thing, I was in a 3 man lobby that had a man join mid game. He asked as to type, as he was deaf and couldn't hear it when we used our mics. The two people who weren't hosting agreed, while the host stayed silent. Flash forward about 10 minutes to the end of the heist, where the host stopped and chatted "deaf people don't deserve rewards" before kicking the deaf heister so he didn't get any money or exp.
That one still gets me because it was outside of the normal, shitty things you hear while playing online. Or at least, I had never heard it before.
