"This may sound strange, but people who I've always considered "conservatives"/"Republicans"/"right-wingers" have started to express some of the most positive and hopeful sentiments."
Why would that be strange? We're watching the left self-destruct as they take identity politics to its inevitable conclusion and start to eat each other. I haven't felt this hopeful since the collapse of the USSR.
The right is driven by love of their family, their nation, and their communities. The left is driven by hatred of anyone who's different to them. The only reason you think it's strange is because the left have had better PR, thanks to decades spent infiltrating the media.
