@pe7erpark3r, you seem to be looking at this as some sort of big picture situation. I approached this as a way smaller picture. I will tell my line of thought here through an analogy. Maybe it will help in clearing out why a did what I did.
Imagine we are on a restaurant with a bunch of friends chatting and having a great time. The place is super busy and filled with all sort of different people. Then comes stomping in mister polish Nazi over there, and starts harassing everybody who is not a white christian in the joint. Then he comes to our table and start harassing our friends. Some call the staff of the place and hear things like "I am sorry but free speech and you could simply ignore him as well". Then they proceed to leave the place. We could spend the rest of the night debating him over why he is a fucking obnoxious moron, or a misguided young man. But that doesn't change the fact we are now alone, wasting our saliva on a guy that is clearly unwilling to talk. Then, we, tired from this whole pointlessly endeavors decide to leave the place as well. But then, something happens... Among the multitude of patrons of the restaurants, there were some that were also bothered by our mixed group of friends, but we're too insecure to say something... Now they start congratulating and talking to mister "Polish fascist" who got rid of the "scum" that were bothering them as well. When we all go back there, instead of one obnoxious scumbag, now we have three. We decide never to go there again. But then they start going on the same new place we choose to hang. We like diversity, so we choose a place filled with mixed people from different backgrounds, and that's the perfect recruiting ground for them, and they always end up recruiting one or two more sympathizer whenever we leave to avoid lowering to their level and keeping our moral high ground. Soon, they are outnumbering us and our mixed group of friends simply by the fact that most of our friends stopped going out for fear of running into them.
Now... If we, on the first time "Polish Himler" insulted our friends and the other patrons would have been decisive, firm, equally as harsh and aggressive as him, and gathered support from the other, non vocal patrons of the restaurant against him, and kicked him out of the place, we would still have a place to hang, friends to chat with on boring Wednesday's evening, and one less "radical" to deal with on our little favorite joint, as well as three or four "sympathizers of the polish extremist" rethinking if they are right simply by the fact that since they are too shy and insecure to expose their beliefs it means there is still room for a doubt, unlike our friend, mister "SS camp guard in the making" who were and probably will be for a very long time, completely possessed by his distorted world view.
I think, if you replace the group of friends with family members, the right choice becomes more easy to identify. Free speech is a two way street. Also, fire can burn both ways and he was a big proponent of "purifying" this place, so I am glad he was the one purged. And I didn't even said anything about he leaving this place prior to his pathetic attempt of leaving with the higher moral ground. I challenged him to a discussion, he left because he doesn't want to be opposed, he wants to be obeyed.
So, yeah, I am not a big proponent of pacifism to be honest, as I think the world would be a better place if instead of being patient and indirectly compliant to most of what we all can agree are bad individuals, we would simply give them a taste of their own medicine, or go even further a little bit and show him that difference between being good and being just.
PS: His last message showed clearly, at least to me, that he has some unresolved trauma regarding being cucked by a immigrant from a third world country because I think he is projecting so much it is undeniable he should seek some therapy. Shadow possession is not a funny business and has been shown to be one of the most dangerous psychological process ever, resulting in things like, you name it, Hitler, Stalin and Mao. So... If you are reading this mister "polish cuckhold", not every woman is like your last one, and not every third world country peasant will steal you girlfriend. This fetish can be cured by therapy, so does your complex. Seek help and live a better life, instead of being the first to die holding a fascist banner in the coming war.
