If the solution was simple, as you said, society wouldn’t be having the discussion or debate.
Of course you still love them...but that would depend on how and what you see as loving them, which would ‘not’ include enabling their behavior.
I do not see Homosexuality as a mental illness...though obvious there are mental issues that result from practicing it. But these come after the fact. IT is a a sexual addiction that begins by making wrong choices until, like all sexual addictions when they take hold, one needs help to change that behavior. That does not mean they are mentally ill.
OK, but part of the problem is that Christian’s let Satan gain a foothold by not using Charity. Someone decided to let the Westboro Baptist Church, later found to be run by an Obama voter, represent Christianity. It didn’t and it doesn’t. There should have been a million Christian voices, extending charity and love, attacking divorce and out of wedlock births, and hammering away on abortion.
What is happening today started at least a century ago, if not further back in US history. A time that most Christians would mark as a golden age. If we cannot do the work of Christ and share his gospel, then we get to the point we’re at, don’t we?
