Saw this article on the Baffler the other day and it reminded me of your thread - "Token-Hunters: Your Friendship Is Not a Gift". It'll give you a different perspective, the minority who has a white person vying for their friendship to meet some sort of diversity quota in their friend group.
Anyways, if you are truly genuine in your search and not trying to progressive virtue-signal, people in this thread already offered good advice. Meetup.com, join different clubs and groups, don't be set in your ways when it comes to new activities. Or even trying for different careers. And hey, maybe try to not be so condescending to your coworkers even if they are "racist Trump supporters", being empathetic and kind goes a long way to meeting new people in general.
