I think it’s pretty easy to just tell people you are not interested. If someone tells me to join knitters group I’d say I am not interested. I don’t knit. Same here. Just not your thing.

I’d be careful about passing judgements though. Unless she condones illegal stuff, I don’t see what morals have to do with it. I don’t see how it makes her immoral. Hopefully everyone in that group is an adult and no one is forced to do anything. So since it’s not your thing just don’t partake. No big deal

I went back and reread what you posted after you received an advice. Apparently this group are all racists and bigots who degrade others because of their MI. You originally said this group was about erotica that you find immoral. You got responses based on your original post.
