Then the two of you are certainly the exception to the rule...because - and this especially true in the age of Trump - it doesn't take a whole lot of brainpower to see that the GOP and the Right as a whole is growing ever whiter. Are you really going to try to claim otherwise?
FYI, I know quite a few white/brown marriages - they're pretty common in the Filipino/American community - and most of the men are certainly conservative (frankly, we liberals are a political minority therein). But again, these are but a drop in the bucket when compared to the Right as a whole.
So don't think I don't understand what you mean - I'm the only 100% white in my family (since all my close family Down South has passed away). In any case, none of this (including your point) detracts from the attitude that the Right has adopted on the macro scale.
One last thing - don't think for a moment that I'm accusing the right-wing rank-and-file of malicious racism - I'm not. It's been my position for well over a decade that the vast majority of conservatives are good, honest, well-meaning people who have no malice towards anyone. The problem is that y'all are being led down a path to someplace none of us want to go. Look at it this way: there is not a single former Republican president of which I'm aware (including Reagan and especially Eisenhower) that today's "conservatives" wouldn't reject out-of-hand as being left-wing liberals and/or socialists. Today's conservatives have forgotten what real conservatism is, and have replaced it with nationalism...and complained not one bit when Trump put an avowed white nationalist as his senior adviser soon after taking office.
I really am very concerned for the Right, because if you'll look through history, in all the great national upheavals (civil wars, coups, etc.) wherein so many were imprisoned or killed, neither side was full of evil people - most everyone were good, honest, well-meaning people who were being led to do terrible things by evil people. Think on that as you see - how you must see - the steady increase of racist dog-whistle rhetoric by those who are most influential in today's American right wing.
