I've known a number of folks who came out to their parents and got fearful and hostile responses — which the parents later apologized for and tried to make amends for. This seems to be a pretty common pattern, in fact. Broadly, people want to have good relations with their families, but they may not always act that way in the moment — and they come to regret actions that harm those relations.

People whose families eventually realized the error of their ways are probably rather more comfortable talking about their experiences than people whose families really did reject them permanently. Suspecting there may be some availability bias going on here.
