Simple. Yes, be hospitable. The chance to correct the error of their ways may come up.

They are the sojourner whom we should help. For God so loved the WORLD...
I think of the way of the Jews, being nice to neighbors, Jew and Gentile but separating themselves.
A good way to do this would be to have LOTS of cookOUTS with neighbors. Just getting around things.
Telling others of God’s love and His blessings is glorifying to Him and is what makes us the light of the world. There are ways to witness, by living righteously, etc., and letting others know that we love our brothers and sisters in Christ most of all.
For how long?
When to we knock the dust of of our feet?
