Here you go:
Mat 7:6 Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.
This is just after the leftists’ favorite verse of “judge not...” Obviously Christ commanded us here to judge whether certain people were “dogs” or “swine,” since he certainly wasn’t speaking of the four footed critters. And He was commanding us to refrain from evangelizing them, which means shunning them. “Swine” is easy. That’s anybody who insists on wallowing in his own filth. “Dogs” is a little more complicated. “Dogs” (kuon) just means “dogs” in Greek. But the New Testament was likely spoken in Aramaic, closely related to Hebrew. And in Hebrew, “dogs” (keleb) is a euphemism for “male prostitute.”
Practically speaking, this makes a lot of sense. Those who love to wallow in their own filth won’t like to be warned of the wrath that awaits them, and also homosexuals are becoming notorious for their desire to “turn and rend” anybody who opposes their deathstyle.
There is a fine line IMHO. When we are told "they will hate you - because they hate(d) me", and also "take up your cross daily...", this is a call to action - to be salt and light.
The closest thing I can can think of - where I think you coming from is Matt 10:14 "If anyone will not welcome you or listen to your words, leave that home or town and shake the dust off your feet."
We need to be careful I think; there are those who will NOT hear, but there are also those whose hearts might be open. I think our default position - with the lost - is to always assume the latter. And then to present Christ with love, care and respect - but with the admonition "go - and sin no more...".
And the bottom: we need to be careful that we don't boast in our "non-homosexuality" - as if were not the recipients of undeserved grace:
1 Corinthians
26 Brothers and sisters, think of what you were when you were called. Not many of you were wise by human standards; not many were influential; not many were of noble birth. 27 But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong. 28 God chose the lowly things of this world and the despised thingsand the things that are notto nullify the things that are, 29 so that no one may boast before him.
