WHOA WHOA WHOA HERE!
In all the debating of terms and conditionals, I think we have lost the original point of the thread.
The main point of the OP (as I understand it) is that the idea of "We need to get rid of the toxic people in our life" goes against the Bible, because missufan01 understands "toxic" to equate with "sinful" and the Bible says we should reach out to sinners, not shun them.
This is easily answered without all this back-and-forth stuff. "Toxic" in this use is a slang term that does not mean "sinner." "Toxic" is a very specific kind of sinner who delights in drama, revels in rebelliousness and disperses dissension and arguments wherever he goes. A toxic person is very much a sinner, but not all sinners are toxic people. And yes the Bible does tell us to avoid those toxic people.
Toxic: Adjective used to describe usually very negative person, that complain about everything, spread unnecessary hate or just talk trash about others. You can meet these people in any online game community.
Synonyms for toxic: Hater, troll, griefer.
Here you go missufan01. I hope this clears up the misunderstanding.
