Christians should love homosexuals; and it is precisely for that reason that we ought to call their sin, sin, and urge them to repent and seek restoration through Christ. What's next - attacked Christians for being 'anti-burglar' for teaching against theft, and claims that Christians 'hate' burglars?
Oh yeah, it will anger them, but the Church certainly can't be faulted. The pastor or Priest can even say “how nice that we have a chance to save all these people today. Parishioners could even surround them, with love of course, with every intention of saving even just a few.
Practice what we preach. A friends parish did exactly this, and yes the activists were incensed, some were dumbfounded, but they eventually left. Any damage they did was outside.
Now if they have weapons, which may eventually happen, that would be a different scenario.
You know, it's interesting. The findings of neuroscience have confirmed what sages have said for centuries: that every sin, vice, or weakness has both an "inborn" and a "behavioral" component. Some people have a genetic tendency toward aggressiveness, others toward sloth. Some are by innate temperament extra-irascible, and others extra-lustful or extra-gluttonous.
Though it's far from proven, it wouldn't surprise me at all if there were indeed some inborn tendency to same-sex attraction.
That doesn't mean "I'm gay, I'm OK, 'cause God made me that way." That means: "Welcome to the human race. You're flawed. And so are the rest of us."
Christianity has a highly realistic approach toward this innately-flawed business. The flaw is called "original sin," the condition is considered universal, and the solution is, you need to be born again.
This is Basic Christianity 101. Anybody should know this.
We don't "affirm" each other in our flaws, our twisted tendencies, our brokenness. Wr acknowledge our problem. We pray for the grace, through Almighty God, to pursue the battle and "carry our cross" every day of our lives, to be freed from our sinful tendencies and live a new life, one which is pure, God-pleasing, and blameless.
