Reactionary, yes, but I don't see how their wanting to classify attacks targeting police as hate crimes indicative of a "deeply prejudiced agenda".
I view it as such because basically no other job is classified similarly to race, gender, etc., so that it would let attacks on the people doing it be classified as hate crimes. It strongly seems like a motion to mirror BLM's calls to combat hate crimes against Black people.
And most blue color workers in the US are conservative, police probably more so, so it shouldn't be a surprise to find Trump supporters and far-right extremists among their ranks. I mean really: where else would they be?
That's a good point. In my opinion, some leftist politicians don't do enough to address the concerns of the average working-class conservative, but then they turn around and talk about all conservatives as if they were a monolith.
Right or wrong, populists tend to exploit genuine issues, so it seems to me that any leftist politician who fails to address these issues in a way that speaks to the average conservative will inevitably lose their support.
