This becomes particularly obvious when people try to start a panic about trans charities or schools supporting trans minors “behind their parents’ backs” as if parents are just entitled to full control by default and would never do anything bad if they learned their child was trans.
If my own father had ever learned I was trans the most realistic range of his reactions would have been between “kicking me out of the house” and “literally just killing me”.
And I am far from the only one in this situation. LGBT people as a whole are disproportionately represented among homeless youth precisely because so many parents are unsupportive. Outright murder is more rare but has also happened before.
It is ridiculous to just assume parents are safe by default.
