Name calling is definitely permitted for some. I’ve been called a clown more than one time by the same person, and I’m not the only one.
My problem is that I don’t know when people are just joking. Just last week one member told another member to F off. I was surprised! These guys might have known each other and no offense was meant though.
I just try and stay in my lane and don’t get into others business or name call. It’s what works for me.
