It seems as insoluble as the Israel/Palestine question when the two "sides" want directly opposing things. I've heard the arguments that trans people "just want to pee" and that "no-one would go through medical/surgical gender reassignment purely to abuse women", plus the mantras that "trans people exist", "trans rights are human rights" and "trans women are women" and it's quite clear that the people who believe these things fervently aren't going to change their minds any time soon.
But to a certain extent, life isn't fair. Not everyone does have equal opportunities. If you're in a gay relationship (and there's nothing wrong with that) you can't have a biological child with your partner; if you're infertile (as I am) you can't have a child at all; if you're trans (and there's nothing wrong with that either) you can't enter the spaces of the opposite sex; if you're British you don't have an automatic right to go and live in the US; if you're short and unsporty you don't have a right to be on the Olympic basketball team - and so on. All sorts of opportunities are denied people at various different points, some as a result of decisions you make (like not studying for a medical degree means I can never be a doctor) and some not (see above re. infertility), and beyond universal human rights you don't have a right - one might say "entitlement" - to an awful lot of things, much as you might keenly want them.
Like it or not, once we end up in these categories we have to accept it. Absolutely no-one is eligible to do everything or to go everywhere. However if you have made a choice - even if you consider it to be more a recognition of something innate rather than a conscious decision - it doesn't mean that you have made this choice on behalf of everyone else. If you have chosen to transition (again, you may not consider it to be a "choice") you can't dictate that everyone else ignore biology and logic and linguistic authenticity and you can't dictate that everyone else will want to celebrate your decision. No, we don't have to accept the "lady bulge", we don't have to accept child abuse under the guise of gender-affirming care and we don't have to accept men in female sports / changing rooms / organisations.
Not sure how coherently worded all the above is, but perhaps it will provoke some interesting debate.
