It's understandable that most young people want to support trans people in living their lives without prejudice from others hurting them.
The language people so often use in this debate - 'support', 'living their lives without prejudice' - is so insidiously manipulative in its vagueness. Of course no one wants to stand in the way of this nebulous support, whatever it is, the language used is so innocent that you can only be a decent person if you agree with that statement 100%, but people don't realise at first that if you want people to qualify you as such - as an ally - you then need to toe the line re: the exact type of 'support' they have in mind. 'If you're not with us you're against us' - this kind of thinking primes us for #nodebate type idiocies. It's sad and ironic that people think support of gender-conforming individuals needs to take the form of reinforcing stereotypes which are based on the matching of sex and the appearance we expect from that sex. Agreeing with someone that their body does not match their mind and what then needs to be done is to radically change their body to make sure both elements are seen to conform to the same side of a conceptual binary that doesn't bloody need to exist - I really do not see that as 'support' - they create the problem. Self righteousness and oblivious hypocrisy, not a pleasant combination. But if you use language in such a way that people can't help but agree with you, but you don't at the same time clarify the actual terms attached to using such language, and where these terms are much more specific than what normal usage of the term entails, and you have the resources to establish yourself as the authority on what constitutes 'support' (e.g. Mermaids UK)...you end up with a situation where you can very easily trap people into being spokespeople for your agenda, starting from when they use everyday words like 'support'. E.g. 'Oh I'm not sure I would date a transwoman' - 'I thought you said you wanted to support trans people'? To the point where when saying 'I support trans people', it will be automatically assumed that your politics are libfem/TRA and not gender-critical. You can condense a million imperatives into ordinary words and have them enforced with no effort by hitching a ride on their emotional pull, which is quite independent of specific context and so not contingent on whether you actually originally believed in the agenda, but rather on whether you're a person who simply believes 'support' is a good thing (99.999% of the population). Of course young people are very vulnerable to this.
