The closest word I can think of is a sycophant but that’s too strong word and not exactly what I’m looking for. The word I’m thinking of has negative connotations and it’s for someone who is friends with different groups but only at a superficial level and isn’t necessarily honest about who all they’re friends with. This person would be seen as untrustworthy.
You obviously don’t know how cults work. But that’s fine. I hope you’ll never lose a real friend to one.
Maybe give it as an example.
you’re planning to spend time debating with a ziganwu? or if you’re western, a staunch far-left or far-right supporter or someone with very racist views?
