Just tried to sign up for me, my 16 year old daughter and 18 year old son to join a one day sewing workshop and the tutor was very unwelcoming about my son joining. She said the workshops are mainly attended by women and the group as a whole might be uncomfortable talking about women's issues with a young man present. I feel really sad about this and so have not signed up.....is the tutor being discriminatory......what are your thoughts?
