Advice needed.

So the workplace I’m at is a very Christian conservative one. And for the most part it was fine until my coworkers started making more homophobic remarks and one day even saying some tin foil hat conspiracy nonsense about how water and processed foods makes men gay. I’m a Bisexual person and truthfully it’s just difficult being in that environment were you feel hated nobody knows I am not straight but if they did I’d worry they’d most likely fire me I just feel miserable and ig I’m looking for some advice on how to deal with people saying that stuff or what to do if they try to antagonize me.
