It's quite unfair to pick that precise example, choosing to forget my complaints (that are very real) about extremely low numbers of women during all my maths/science studies and job path. We didn't want to be just between men, neither in college or uni, nor at work - it's just as boring as being all day long, for years to go, only between women :)

Of course, which is why you don't solve this with policies and laws, but education. I already gave you the example of far-right people still managing to pass a message. At some point, when ugly words are avoided, you go into process of intention, you assume evils and ill will automatically, because it fits some activist mood (or worse, feeds activist funding, or serves some political purpose).
