So I was using a mental health chat support group on messenger for about a month.The bloke that formed the group and ran it kept seeking praise for setting it up and kept calling it my group like he owned it.He and his wife monopolised the chat.I got on ok until we turned to discussing the football and some fans at my pub singing the national anthem,I said I hated Nationalism and wasn't a monarchist,so the group owner pipes up how he and his wife love the royal family,so there was I an outsider,but I shut up and left them to their beliefs.The otther day though one of the members said she was playing in the sand pit with her kids and sand got down her top and she wanted a shower to get the sand off her tits and our beloved leader said we ought to call you that as a nickname and he gave her the nickname in the group of Sandy Tits and changed it on the group settings to that.I objected and said I found it offensive and sexist,he apologised but denied being sexist and removed the name along come the group flirt another woman and challenges me its only a joke don't accuse him of sexism blah blah blah and she inflamed the whole situation.I insisted it was sexist and inappropriate for a mental health group where people had been abused and needed safety to refer to a woman by her body parts.They insisted it was a joke and not sexist,I said they had a blind spot.The man liked smutty jokes and nicknames and he claims he is not sexist is it me or what?In the end he said **** it I am not having this ******** in my group and blocked me.Because I have no access to the group chat page to link it and report it to Facebook he has got away with that.But I am disgusted and upset.I feel he hasn't wanted me in the group since I said I wasn't a monarchist.He was the one in the wrong and I get blocked.

Why do I lose the support when he is the one that behaved inaproppiately?
