Why can't you be opposed to the "policing of the gender binary" - which feminists are - without it affecting your sex?
If you say that stepping outside a stereotyped gender role means you are not the right sex, then you are policing a gender binary yourself.
Trans ideology needs to build a false world in which there are two strictly policed gender roles for men and women which no normal person ever deviates from – which is in fact totally untrue - and in which anyone who questions trans ideology is part of a deliberate transphobic movement. Spearheaded by, um, lesbians and radical feminists, who always supported gay rights and trans rights until we had our own protections systematically removed. Along with some trans people too.
It's not anti-trans or transphobia. It's anti-ideology, anti-bullying, anti-having-lies-told-about-us, nonsense-phobia.
Meanwhile there are actual transphobic people around who trans people really do need protection from. Why not work for a way forward where we all get our protections, rights and as much safety as possible?
Harry does say research is needed, and I totally agree. Bring on the research, into the effects of cross-sex hormones and surgery, the outcomes, the suicide and self-harm and depression rates for different approaches, the representation of equality laws by trans charities, the funding of trans charities and who is making money from all this, the rise of being trans as a fashion statement in schools, the numbers of people who wanted to be the opposite sex until they grew out of it and whether they are happy with their sex now. It all needs to come out and transactivists need to take notice of the facts too,
