You're basically saying "There isnt anything inherently wrong about working for the 4th Reich"
Not all LEOs are brown shirts, In my experience, few are, but they give the lot a bad rap.
Treating LEOs uniformly as evil is just counterproductive
No one becomes a cop because they want to be nice and help vulnerable people. Some might say they did but that is some coping technique. Being a cop involves exerting violence towards people who are vulnerable and desperate, and to become one you have to be fine with this. Some would say that this alone is enough to deem a person ethically dubious.
Even if one would accept the premise that society requires some degree of organised violence towards its members, one would also have to handle the question of accountability. Reasonably this violence should be accountable in relation to the victims of it, and police institutions inherently are not.
I think that we should also note that the other person above used "childishly" to denote something negative, apparently they don't think of kids as the light of the world and childish as something fun and inspiring. This is something that makes me quite suspicious of their morals.
I strongly agree. There's even the argument to be made that if no legislation exists, even if you're anti X, you might get incentivized to build a company for X just so it's not a fan of X at the helm of the top company for X.
Blaming it on the employees is pointless. It's the law that should dictate what's allowed and what isn't and if the lawmaking or enforcement isn't working you probably want some "good" people in those companies.
