I mean I still "believe in" "western civilization" because our history is so rich, and it's worth noting we had all kinds of polities ranging from absolute monarchies all the way into ancapistans, with everything in between. The unifying trait of them all is that whoever was running them was White Christians, and usually Men. I also "believe in" "America" even if it's going down the tubes now, we legitimately did have a great run in the 19th and 20th centuries, and I think that one of the few complaints I have with the dissident right today is that guys are so disillusioned with the present that they're willing to throw the baby out with the bathwater on the past. I'm still going to enjoy 20th century Americana and I don't care that it makes me a 30yo boomer lol.
I also think we're likely going to be one of those pioneer-type generations, or our kids will, that ends up building the foundation to the successor-state of America. Something a little more modernized, you know? A little more with the times. But still spiritually our own.
