So what strikes me as interesting is that the protestors against Trump and his cronies speak as if it's about real moral values---that it's not just conditional. For example, feminist protestors will say women's rights are human rights. To me that just sounds like religious faith in something that hasn't been proven.
I liked your second comment about emotion. It could be that many of the protestors use language that sounds absolutist (as in "black lives matter"), when in fact they are just using strong language to make a strong impression. I'm sure it varies from person to person.
Anyway, I'm a little torn. I hate Trump. Mostly because he's an idiot who will ruin my country if given the chance. On the other hand, I shy away from the group mentality of the leftists. They can sound very religious to me when they talk about group identity, rights, sympathy for the weak, equality, etc. But for the moment, they are much more appealing to me than Pence, Trump, the alt-right, racists, etc.
