Why are people so amused by their own suffering and bondage?

Making choices for oneself is very scary, so people delegate that responsibility to Uncle Sam so they don't have to worry about decision making.

Why are they amused by warfare and bloodshed?

Because my team is better than your team, obviously.

Why do they idolize violence and viciousness?

Probably because they are insecure about themselves and resort to bullying by proxy to feel superior.

It’s my hope we can abolish government and rid ourselves of political enslavement once and for all.

If everyone was well-educated and had good social games such a situation might make sense. Unfortunately, not all sheep play the rational game. I've played games against emotional game. Those games are unpredictable as hell and often you get screwed by the stupid guy. Having social contracts is good as long as everyone has the option of opting in and out of them more freely.
