A lot to unpack here. This thread is becoming emotional, and I like you as a poster, so please take this in the spirit in which it is intended; good faith dialog.
First off, the people here who are posting in full support of this particular group also say "I wouldn't recommend joining", "I'm not telling people to join" etc. That's not exactly a ringing endorsement. If this group is legit, shares your principles, and you think they are doing good, why wouldn't you recommend that people join? Why wouldn't you do it yourself? Calling people cowards for not supporting a group that you yourself wont join doesn't seem quite right to me.
Second, the "fed question" is only the tip of the iceberg when it comes to these types of groups. There are legitimate questions and concerns. Is what they're doing actually producing results? Do they have mass appeal? What are they doing differently, compared to other groups from the past that have failed? There have been many. It's easy enough to gather a small number of people from the internet to march around and demonstrate, but then what? I think they also have issues with presentation, ie the uniforms. Average people probably see it as intimidating and unrelatable. It creates a negative association. It appeals to certain people but I think it's a small pool. I understand they wear masks to protect their privacy but it also makes them seem untrustworthy to normies. Their presentation needs to be beyond reproach and relatable to the average person.
From what I've seen, they seem to be more divisive than uniting. Perhaps that's by design? The rhetoric from supporters and people from adjacent online circles is always about how they're so much better than "those dumb conservatives", which is a 100% losing strategy because in order to succeed and actually gain some degree of influence, you will need at least some of those very people that they love to talk down to, insult and alienate from their cause. This is a problem with all of these insular online right wing political factions. They gain enough of a following to be noticed and make some noise here and there, and then stagnate.
I have seen Patriot Front in the media, and it's always "look at this group of evil fascist/racist/whatever boogeymen, your family isn't safe, be very afraid, we need to do something about this". I don't for one second think that Jews/elites/three letter agencies are afraid of Patriot Front as an organization. They may be concerned about their message, and them speaking the truth out loud, but I think they have the confidence that they can control the narrative, whether that confidence is misguided or not.
Now, if I'm wrong about this and they manage to start waking up large numbers of people to the realties that we're all facing in America and the west, and start producing results like improving communities, I'll gladly eat my words. I'm just going off of my instinct here and past trends.
