I'm going to be the skeptic here and doubt the following:
>1. Everyday they spend literally hours talking about weird conspiracy theories and talking bad about black people, women, gay, muslims and so on.

Because you don't get things done talking literally hours.

>2. the CEO and the other employees

Because this is such an archetypical "Me vs the world" situation, you're giving everyone that's not you the same label.

>3. weird conspiracy theories and talking bad about black people, women, gay, muslims and so on

Vague and typical "Me vs the world" again. When people have biases they're usually very narrow, to have "everyone except you" have a large amount of biases against many groups and, again, everyone except you is like this, to me it sounds like you're quite eager to label them.

Either way, it seems that you don't fit, so you got the choice to not interact with them (you will likely become replaceable fast if you isolate yourself) or take your leave, if it's indeed such a stagnant place then nobody has a professional future there.
