Tips for trying to keep job

What things are there to do thatll get me close enough to them so they dont single me out and i get fired but not close to be friends? I dont really want to be friends with them. I mean only a couple of them actually want lgbt dead but the others often make jokes and views us as lesser, doesnt mind the death they joke about it. Even if i could lie i dont really think i could hold that image up very long. Now i just stay quiet about everything but i dont want to be singled out. Can i do like anything like bring like snacks etc. where they wouldnt do that but they wouldnt get close at all and wont find out anything?
