The Question is rather simple: should I as communist (and a Brazilian) own a gun? I'm not going to lie, I like weapons and the art that is making them. That's the only real reason I wanted to get a gun license. I wanted to collect old Soviet weapons and maintain them for the sake of it.
I'm also new to socialism and communism in general, so sorry if I'm dumb by asking this
More important to organize. PCB-RR is currently your best bet if my info is correct. Having something by yourself won't bring about revolution. That said if you get a gun you must train with it and be able to use it effectively in situations that are similar to real combat. Once you have the skills you should train your comrades.
Firearms aren't the only thing you need for a revolution. Logistics, communication security, explosives, drone piloting, fortification, moving secretly, organization to limit impact of infiltrators, and close quarters combat are all important topics of study for a people's war of liberation. This is all hypothetical of course.
Do they accept new members from outside main PCB currently? I was under the impression that still needed to be sorted out in the assembly in June. Asking for a friend.
It seems they are accepting new members but the on-boarding process will probably take some time due to the ongoing party split and the chaos and difficulties involved in properly dealing with the old party.
I don't know one way or another as I'm from the US and not part of the PCB-RR. But that's definitely what I'd start with. If you don't hear anything back come bother me again and I will bother my contact again.
