Question Time having a womans only panel

OK so if there is anyone in the UK here that is interested in politics I don't know since very few people are interested in politics these days.

But in case there is someone who fits that description - what on earth was up with question time on Thursday having a womans only panel?

Surely that is discrimination and with everything these days being discrimination then it should not have been allowed as it prevented any men from getting in which is ridiculous in this day and age!
