I have decided human beings cannot change sex - they can have hormones and plastic surgery, but they remain their birth sex in every cell of their body, in their skeleton, musculature, endocrine system - none of which can be changed to the other sex by any medical or surgical means, @Darker. Can you prove otherwise?
I have decided women and girls are safer if spaces like changing rooms, toilets, hospital wards, prison cells remain single sex, and no male-bodied people are allowed in. Can you prove otherwise?
I have decided that trans ideology is deeply rooted in old-fashioned, toxic stereotypes of masculinity and femininity, and it is far more progressive to say that a boy can like pink, skirts, frills, make up, long hair and hate rough sports, getting grubby, rough and tumble - and this doesn’t make them a girl - they should be allowed to be a boy with their own individual character. A boy/man is someone with male biology and any character, not someone with any biology and a masculine character, and a girl/woman is someone with female biology and any character not any biology and a feminine character.
