Or, you end up in the hospital with a TBI, like that wannabe-badass antifa dude who toppled right over, flat on the pavement, when a Proud Boy with actual fighting experience punched him. The video of that incident is a fucking classic, because it shows just how little substance there is behind antifa posturing, and pretense that they're an actual threat.
And I would be more concerned about some dumbass Lefrard like Isaboy bringing guns to a protest than the Proud Boys or Patriot Prayer, since most of these Lefty mongos are mentally and emotionally unstable and have a massive entitlement complex, so they would be far more likely to feel justified in publicly pulling out a firearm to intimidate or kill anyone who doesn't agree with their political views. The Proud Boys and Patriot Prayer members likely grew up with firearms and know how to safely carry them. Not only that, but there's no way that they would jeopardize their image, risk losing support, not to mention risking getting arrested, by arranging for all the permits and everything to publicly demonstrate, then pull out a firearm to intimidate or shoot people who have differing views.
Here's one thing the right does so much better than the left that it's not even funny: group cohesion and discipline.
On the left, everybody's a special, one-of-a-kind individual, totally unique, and while they will cheerfully be "allies" to a group or cause that feels good and sends the correct virtue signals, they have absolutely zero cohesion as a group. Even when they do manage to act in a cooperative way for one event, the bonds between them are so fragile and easily splintered once something is deemed "problematic"--just look at the Women's March, and how "pussyhats" were declared problematic after troons complained that not all women have pussies. As a group, the activist left isn't a group at all; it's a collection of people with various grievances, battling for dominance under the guise of "representation," and even if they can be convinced to show up in one place and time to square off against a common enemy, the best they can do is show up en masse and make a show of it. And as soon as the show ends, they're going to go right back to policing each other and fighting amongst themselves.
On the right? People are used to subordinating themselves to a cause or institution that is bigger than themselves, and often multiple, overlapping such institutions. It may be Christianity, where the individual is part of the body of believers. It may be family and the bonds of kinship. It may be the military. It may be a rural community where people have traditionally assisted each other in order to survive/thrive, and they take pride in that shared history, social cohesion, and neighborly cooperation. It may be patriotism, in general. And yeah, it may be something like White Nationalism, where the individual identifies strongly with being part of a race or lineage with its own identity, traditions, and culture. For some people on the right, it may be all of those, but for a lot of them there's going to be at least two or three.
So the right is much better at pulling together a large group that will actually behave themselves because they see themselves as
members of that group (rather than mere "allies"), with strong shared values and interests, with more goals in common than not, and they don't want to fuck things up for the group by getting other members hurt or making the group look bad. When the Patriot Prayer folks have showed up in Portland, they've got organized leadership directing the movements of the group, and the group actually follows orders, and they've all decided they're okay with that.
I don't see that level of group cohesion, and willingness to follow orders to act as an organized group,
anywhere on the left--and there can't be, because the left is so fragmented by identity politics, and nobody's willing to give an inch in order to potentially take a mile. Even Antifa, for all its posturing as a cohesive group with a strong identity and mission, is loaded with snowflakes who just want to do their own thing; if Antifa leadership told them they couldn't smash windows, get in fights, and destroy property because that was counterproductive, they'd all abandon Antifa for a new group that would allow those things. They really don't give a shit about the group and its goals, only their own individual chance to get payback for imagined wrongs. And while they enjoy the anonymity that comes from wreaking havoc within a group of identically masked and black-clad allies, every damned one of them is strictly out for themselves, and won't be told what to do.
