Yes, his is fascism and should not happen.
However...I do think that the left lives in a bubble sometimes, and fail to get tracking amongst the working class. Working class people really do want proper police protection, and deserve it.
Sure crime statistics are down, but everything has become very uncomfortable. Some homeless guy gets on the bus, drunk, with his stained clothing inside out, and maybe on drugs and now you have to worry if they are going to stab you.
Yes, police should not harass homeless people, but now you have 20 average people on the bus worried that they'll be stabbed. This mild level of anxiety is constant.
The left has asked the working class to take on a disproportionate amount of burden, yes it's better to have out treatment for addiction, and not arrest the unhoused, but the working and lower middle class do feel the pinch of this policy affecting them.
The working class, blue collar residents, see Trump make these proclamations and desperately hope something breaks in their favor. It won't Trump is not a capable manager.
