The change of one administration to the next does not erase events from the previous one. This guy was a conservative, given statements from his classmates saying that explicitly, so obviously it was not in revenge for J6; I'm not sure where you got the idea I was arguing that? I'm arguing that political violence (by Republicans) exists in the status quo, prior to this other Republican's actions.

I think you might not be that different from a Republican on this one

Republicans are mostly neolibs, same as Democrats. But yes, LibLeft philosophies like Anarchism and LibRight ones like Libertarianism both tend to be suspicious of government, and AuthLeft philosophies like Marxist-Leninism, Centrist philosophies like Neoliberalism, and AuthRight ones like Fascism, all are big on loving (their) governments.

States are also the ones using public money to fund healthcare centers, centers for people in need (eldery, women escaping abusive relationships, unwanted children), they are also making the public space more accessible for people with disabilities, they are providing public transport options for people unable to ensure themselves this option, sometimes even providing means of communications (through mail for example).

You are seeing states do those things, and presuming (I'm guessing based on where you live) that those actions are therefore the actions of states. They're not, they're the actions of a community. When you belong to a community that a state supports, it provides those things that all communities provide. When you don't, they don't.

these sometimes provide better options than letting individuals work by themselves in order to solve these problems.

Are you under the impression that the only alternative to "Modern Western State Governments" is "individuals work[ing] by themselves"?

If you’d ask me, I would feel safer in this regard when accessing these services provided by the state instead of relying on a fringe (sometimes) armed group, looking to gain power for themselves.

I hate to break it to you, but states are just very large armed groups, the legitimacy of which is entirely determined by their strength of arms. Israel kills far more people than Hamas, under at very least equally-questionable tactics, but Israel is a "legitimate" government because they have enough guns (and enough friends with guns) to force others to acknowledge them as such. If Israel had no friends and a weaker military than their enemies, they would be considered a "rogue" (or as you call it, "fringe") state. This is precisely why "pariah" states pursue weapons programs like nuclear arms; that lends them legitimacy in the Statist, Neoliberal world order.
