It's a bit of a contradiction... in the defense of a variety of views coming down hard one a view... particularly a sincerely held Biblical view
So you'd be happy for Christians to champion what used to be one of their favorites, Thou shalt not suffer a witch to live?
You see no problem with advocating to bring back slavery? Slave-owners were fond of quoting the bible because it was so specifically, frequently and enthusiastically on their side. Even Paul (Jesus doesn't mention it).
And you remember
Why Can't I Own a Canadian?, of course, which seems particularly topical here.
Just because it's in the bible doesn't mean it's a good idea. There you can find support for invasive war and land grabs, the massacre and/or enslavement of entire populations, the mass rape of women, for human sacrifice, polygamy, religious intolerance (in spades redoubled), the death penalty for disrespecting your parents, for cutting your beard, on and on.
And although nearly all of that (the human sacrifice of Jesus is a major exception) is from the Tanakh, the Jesus of Matthew (5:18) and the Jesus of Luke (16:17) say that the Law will not be altered even in the smallest degree till the Kingdom is established.
So Christians like Bill should either advocate for the lot, insist that their country, Canada or whatever, follow the Law on those points; or else they should stop cherrypicking simply to justify their personal homophobia.
