GOP hasn't been pro-gun since before you or I were born. Just because they block (some) of the democrats dumbest gun-laws doesn't make them pro-gun at all.
Acceptable, sure. I do not care that he's dead. But it seems unwise on Luigi's part to throw away your life to kill one CEO who's going to be replaced by someone just as bad.
The thing i dislike the most about luigi is that he got caught when he was almost certainly should have gotten away. But maybe the trial will be some kind of transformative re-interpretation of self-defense or something (I doubt it).
In a vacuum, yeah trading out anything 1:1 is a generally naive and unsustainable strategy.
If, however, we use the context of socioeconomic class warfare, it is a brilliant strategy for the working class to trade 1:1 whenever presented the opportunity. Due to the sheer population advantage they have.
