So are you're saying that expressing the Christian view that God intends for men and women to only have sexual relationships within [a heterosexual] marriage, that such marriage should be the basis under which children are raised, that marriage should be a singular unending union, expressing such things won't cause one to be vilified, on HN say?
I'm going to go out on a limb and suggest there probably isn't one person posting on HN that has ever interrupted a wedding to complain that all the man and wife stuff is a bit heterosexist.
Surprisingly, HN - atheists included - is both capable of celebrating people's happiness when they express views on the amazing "god-given" nature of their romantic relationships, like Tim Cook did, and disapproving of people making statements to the effect that other people's romantic relationships are wrong, like Tim Cook didn't.
Equating the two is a desperately poor excuse for an argument.
The evidence seems to be against you.
