basically, we just need to look at a fellow Jew as a fellow Jew who is also special and important. We each make our own contribution in life and we are all needed to complete the puzzle so to speak. Someone might be different, but we can still be nice and respectful eventhough we have a different viewpoint, litvish, chassidish, sefardic.
And if the person is not religious, we should be friendly so maybe they will someday be inspired to learn and grow
that’s what i like about shabbat.com where hosts and guests are put together
