It's a matter 1) letting the Spirit be the testifier/converter, not us. And 2) just because you disagree with someone doesn't mean you're not off the hook for understanding and loving them.
My point is biblical love does not equal agree with error.
If I respect you as a person, that would mean getting to truth. If you hold error and I do not confront you and let you go to perish, that is not love
then we would say, we loved jane doe, she was a nice person, except for holding false teaching, she will be one of the nicest sinners to perish, however, and it was nice to chat with her???
No..many do not see this as love. A believer who does not seek to inform others of truth, is not loving at all.
