“Why do you care?” is not an argument. It is an attempt to shame and scold people out of discussing policies that affect language, law, sport, prisons, safeguarding, medicine, schools, and women’s rights.
If it shouldn't matter to me then it shouldn't matter to anyone, so what are you doing here? Women are allowed to care about the definition of women. Lesbians are allowed to care about sex-based boundaries. Parents are allowed to care about safeguarding and medical ethics. Women and girls are allowed to have boundaries, to have those boundaries respected by men and boys and to be concerned when their reasonable concerns are ignored and shot down by some random woke scold with "Why do you care?"
Calling that “obsession” is just a way to avoid answering the actual arguments or engaging ingood faith.
And if this is supposedly no big deal, then it should be no big deal to say sex is real, women are female, and gender identity does not override everyone else’s rights, language, or boundaries. If it's no big deal for women to be redefined, then it's no big deal to not do that shit, too. It really should be no big deal to say sex is real and the infalsifiable gender identity of a tiny monority does not override everyone else’s rights or boundaries.
Speculating about my psychology instead of answering the argument is just name calling and bad faith concern. Women are allowed to care about laws, language, safeguarding, sport, prisons, medicine, and sex-based rights.
"Why do you care?" is yet another deflection, ad hominem, and attempt to suppress the argument rather than addressing the concerns in good faith. Thank you for demonstrating my point about common rhetorical tactics of trans activists in this exemplary example.
