What are your thoughts on the Alt-Right, and how can I be a better ally to Jews?

I have been a life-long supporter of the Jewish community and would like some advice. The title is pretty straightforward.

P.S. I am not a troll (just look at my post history).

Thank you! 🙂

Edit: The poor phrasing of my questions suggests that I am a part of the Alt-Right. For the record, I am not.
