You ask “where is the condemnation”, but the example you give, which is horrendous, is 35 years ago, and this is rarely seen today. Murder of the innocent & especially hate crimes - when it happens - is universally condemned, and has been for a considerable time. Similarly for explicit forms of unjust discrimination. Condemnation is swift and clear, and the reason we don’t hear about it so much is that (thankfully) there is hardly anybody about arguing the opposing position - there has not been a “pro violence / pro unjust discrimination toward gays” movement of any substance for a very long time.
All of which is good.
First of all, hate crimes against LGBT peoples still happen, even in the Western World, not to mention Africa and Middle East, especially. Many Americans know the name Matthew Shepard, but most do not know that the murder of LGBT peoples since that horrendous event, even in the West, number in the hundreds.
I think you’re missing the point completely. Many on this forum decry the state of our society for accepting gay relationships to the point of even tolerating gay marriage. We should not allow gay marriage, as a legal matter, they say. We should not approve of homosexuality, as a societal matter, they say.
What they do not say is that we have seen and know well the world they envision, because it is the one in which we were all raised. We know what it looks like. And it is a world in which, not only are gay people discriminated against, but even when they’re lives are taken in violence, there is no outcry of injustice when the sentence is obviously unjust.
And what explains this change if it is not acceptance? Did Christians, without provocation suddenly come to the realization that discrimination and violence against gay people is unjust? Or is this changing view in the West, prompted by the LGBT community, primarily responsible for this change?
Where would we be now had we never been challenged? And what makes you think there would have been any change if our society had not been persuaded and instead held strong to its view that homosexuality is sinful, evil, and worthy of condemnation?
