I think what a lot of people don't get
or are refusing to see is that expressing prejudice through religion is just
one framework through which we as gay people find ourselves on the receiving end of homophobia. (Which, when you strip everything else away, is basically fear and weak-mindedness, in my opinion.)
It comes in many forms. Religion 'it's against God's will, the Bible forbids it', etc. Medical 'gay people spread HIV'. Statistical 'well there's only a tiny percentage of you, you don't matter'. Societal 'I don't want my children exposed to that'. And so on it goes.
Some people will find whatever convenient framework that works for them to justify it, but the end result is the same: alienation, prejudice, rejection, hatred and sometimes violence.
That's why this situation is shit. Because Luke and Lachlan have probably experienced bits of shit chucked at them like this their whole lives, but with varying justifications.
