Progressive's are not typically pro-gun and these individuals are fighting to up hold the constitution. Name one shooting at these events.
If you go to a political rally its the Left who are spitting, fighting, screaming, and assaulting individuals. Antifa anyone.
Especially in today's political climate, I think it's important to distinguish between "liberals" and "leftists" in America, as people tend to think they're synonymous when they've become entirely different animals. Classic liberalism was based on freedom. The classic liberal was an individual who wanted to fuck whoever he wanted, eat/drink/smoke whatever he wanted and the government stayed out of his business. This has largely morphed into the current Libertarian movement championed by guys like Ron Paul.
Leftism is an entirely different political wing, and goes against everything the United States was founded on. And those idiot fucking pussy "antifa" kids with masks on raising hell in public because somebody hurt their feelings are a good example of what it's become in America. They basically follow a simple set of ideals:
1) The government should control what you have and make sure everything is equal.
2) If you have more than me, the government should take it from you and give it to me for free because that's fair. All rich people are racist and fascist and became rich by oppressing someone, usually a minority.
3) The government should control what you think and say. If you think or say something that offends me, you're a racist/fascist and the government should punish you. The First Amendment is racist and outdated.
4) Everything should be free for me. Insurance, college, bills, rent, and if you disagree it's because you're a racist/fascist.
5) All weapons should be banned. Only the government should have weapons. The Second Amendment is racist and outdated.
6) Anyone who is suspected to be racist/fascist is subject to government intervention. The Fourth Amendment is racist and outdated.
7) The entire U.S. Constitution is racist and outdated. After all, it was written by white people so it must be fundamentally racist and fascist.
8) If you disagree with anything above, you're a racist and fascist and probably a tool for Wall Street or corporations so I'm gonna put on a mask because I'm a fucking pussy and don't want to be ID'd by the cops and then I'll come in a group of a hundred to vandalize your house and break stuff and then brag about it on social media. My Facebook account lists my occupation as "social justice warrior." I don't really have a job.
I would categorize myself as an extremist Libertarian Capitalist. I will always resist taxation without representation, I will hoard money, I will say and publish whatever I like and I'm so long as I'm not hurting anyone else and engaging in such activity on my own private property and at my own expense, I'm going to eat, drink, smoke and fuck whoever and whatever I want and I'm also going to stockpile weapons and valuables because our constitution guarantees my right to do so and if you don't like that then try storming my house on your own to violate those rights and see what happens to you.
