I defend people's right to say things that offend me, providing they aren't threats or an actual hate crime
- which the police admitted this wasn't
I would defend anyone's right to free speech - left, right or centre, religious or atheist

There is no way to swap chromosones
By definition, women & girls are homogametic, i.e. with two of the same kind of sex chromosomes, XX,
whereas boys & men are heterogametic, i.e. with both X and Y chromosomes, typically XY but very occasionally XYY or XXY
(For birds, some reptiles & insects, the females are heterogametic with Z and W chromosones; however, this is not the case for mammals)
