It pains me to say, but I think you are right. The dismal tide is not just a fun quotable from that one movie; it's the inevitable change made up of the critical mass, and when you are part of the rock at which the wave is incessantly crashing into, and which will eventually be overcome and toppled, you should not ignore what's right in front of you.
There are two main, undeniable truths as I see them today:
-Demographics in America have and will remain changed, in a way that is not positive for a lot of folks who have found some privilege and comfort playing by the old rules, to the detriment of those now emboldened with numbers and allies.
-Mainstream culture and the zeitgeist of America has changed with the above demographics, and will continue to do so, thus changing the rules.
So my reasoning is to simply learn the rules of the new game and work towards finding something you can live with.
Hanging on to an old model of thinking and living is fine-- it will make for some great parties and the art will be delicious (as creative things, like spiritual things, usually thrive in the margins), as well as the exclusivity will be charming as time continues to march forward-- but one must rid themselves of the mindset of "ought and should" and not be resentful or upset when things don't align to their worldview. It's a necessity if you want to avoid being eaten up with negative emotions and ugliness like you see from the likes of some on this site.
The challenge, and it's more important now more than ever, to be of a growth mindset. Find what good you can with this new wave and try to adapt and find pockets within these people and these new ideas that you can be comfortable living with.
And above all take comfort that from this progressive revolution, as it normalizes and becomes mainstream, there will be opportunities. Human beings are human beings, and life--corrupt judges and politicians-- will, uh, find, uh, a way.
