@Terry I also had a good time in the UK when I was 21. I worked there for a while and they were not as sexist as our blokes... as a vague generalisation ... there are exceptions to every rule.
Most people have difficulties with being in groups as everyone's "belonging" sense is triggered.
Earlier this month a psychologist policy maker in Canberra confessed to me she had difficulties in groups which is why we both opted for a non dorm room in my music course in NSW. She tested the waters out to see if we could be "partners in crime" her words. Then she said in a chatty tone about me doing music with a bad neck "Your mad" to which I promptly replied "Yes of course .. I am the daughter of 2 schizophrenics and married one." Poor lady ... all she wanted to do was sleep ... it was out of my mouth in as chatty a tone as her openers. We settled it by having single rooms next door and being chatty throughout the course but not too close. I actually probably need the single for my neck but it seemed too big a spend. I felt ok in being authentic, and she had a very gentle persona which I need as too much carry on puts my neck out. She also knew a lot about Forgotten Australians in a theoritcal manner as her friend was working on it in Canberra ... so she got to meet one irl.
In my late 20s after Pol Sci degree, I did a lot of group theory and practise in Psychodrama. It helps not take others' issues as personally as I used to. I introjected everything ... was introverted and painfully shy.
@Former-Member's take on the guy in bible study is spot on ..
@Terry its up to you what you do .. but if you like the group generally and that one incident got up your nose ... it could be worth it to stay ...
there is the norm storm perform elements in groups. He might not realise how much it effected all your other feelings and interactions ... which sounds perfectly reasonable to me ... and others may be conscious or unconsciously effected too ... maybe you can broach it gently with him one to one... rather than letting it build up inside you.
I am a bit naughty now ... and feel "god" wants me to improve some of his little groups on earth ..or why did he make me this bloody way ... though I also am bereft when I spit out more than nice good manners ... but I have been known to tell it straight in my very polite respectable church choir ... the conductors dont refer to the females as old chooks anymore . ..
The Moreno Institute has great ideas but the founder was as paranoid as hell. We are all just peeple.
