We cannot base our laws, policies, and societies on clear absurdity.
We just can't.
Because it is absurd, it requires coercion to uphold. So it fucks up freedom of speech and expression.
Because it disadvantages women, and girls.
Because it creates safeguarding loopholes.
Because it is wrong. It is false.
I don't honestly know anymore, OP, why I care so much, only that I know it's not TRUE.
So, pedantry, and a staunch commitment to truth, are my two main reasons. Although feminism and common sense are also involved.
And tbh also once one moves past the basic arguments, their absurdity, and gets into the violent, aggressive, and twisted antics of genderists, it does become more of a moral thing. And then once one sees some of the people who are pushing the genderist ideas, it becomes quite disturbing. Once you see the dynamics, the abusive nature of them becomes very very clear.
I see Eric Joyce is criticising women for wanting single sex spaces. Why is that?
