So three assumptions
1, the only possible reason for a man to wear a skirt is to draw attention to himself.
2 He draws attention to himself and doesn't care about the needs of the children
3. He doesn't care about their education either
These 'assumptions' are potted and selective preces of what people have questioned, based on assumptions of your own and prejudice about the posters who raised the points.
All prejudice is based on assumptions about an issue and involves an opinion formed without reason.
True, but hilariously ironic in the context of your post.
As for the issue drawing attention to him. It really isn't his fault if some GNers are a bit obsessed about men wearing skirts.
Can you define 'obsession' as you are using the term here, please?
(Isn't it victim blaming?)
Who do you see as the victim? Without more details about the story, it is impossible to know whether that would be the teacher, the children, or someone else. If the teacher, of what is he the victim? Did someone force him to wear the skirt? Possible, I suppose, but probably unlikely.
and some also want to introduce fetishes into the issue.
'Some people' have suggested that we are in a climate where drag queens are reading stories to children, and children's library books are showing older men in bondage gear. Is it 'introducing fetishes' to be uneasy about a male primary school teacher wearing a skirt in these circumstances?
