I think Chris Hayes summed it up nicely in this thread Neil M. Gorsuch joins Supreme Court scandal parade - #3 by citizenschallengev4 when he said his thinking on the change that’s occurred over the last few decades is a “complicated emergent phenomenon of an open society”. Not everybody can process that. For people like DeSantis, it seems like he’s just going for power by using hot button issues to get a block of voters on his side. But, you can’t prove that, and people believe him, and maybe he believes himself.
The question for me is, are there “plenty of people”? Let’s say it’s as much 1/3 of the human race that are beyond being reached. Maybe that can be improved but it’s not going to happen overnight. Still it’s still a 2/3 majority. A lot more has been done by a lot fewer.
