>>837794Nope, all of this is total nonsense.
Firstly, on 4chan, /pol/ was always a battleground between various different ideas coupled with the typical shitposting and general bullshit memes you'd see on 4chan. The two groups with the most sway over the board's culture were always the National Socialists first and the libertarians second, and yes, they were two separate groups. The libertarians did not "become National Socialists", in fact they were often very hostile to each other because each group saw /pol/ as "their board", libertarians would often throw around the word "stormfag" as an insult for the NatSocs and the NatSocs in turn would throw around the insult "lolbergtarian".
The differences between these two factions of the board culturally were essentially that the National Socialists would not really discuss politics at all back on 4/pol/, all they would really do was post Happy Merchant memes, infographics about the holocaust, and call everyone a jew. The libertarians were the guys actually discussing politics and economics, and credit where credit is due, they were pretty good debaters. Go to an archived thread from /pol/ prior to GamerGate that is dedicated to the discussion of any political ideology, and it will be full of libertarians ready to debate it to death.
Now, this anon claims /pol/ eventually coalesced into a National Socialist board after everyone else either converted or left, because /pol/ "was a crucible for truth" (not sure why 8gaggers expect us to believe this narrative when 4chan as a whole has been known to be a hub of bullshit and retards since its very creation, and its users took pride in this. There is literally no reason at all to believe /pol/ would be any different, but oh well.) But long story short, this is also unfounded. Not only is 4/pol/ not a monolith (in fact many of the libertarians who had been there since the beginning are still there to this day), but you'll also find if you comb through any archives of the board that it just never was at any point.
Now, I think the paragraph about all the communists, liberals and libertarians leaving is referring to the creation of their own boards on 8chan, and this actually has a really simple explanation. And no, they did not leave of their own accord.
What actually happened is that 8/pol/ essentially dropped the free speech ethos of the original 4/pol/, and so you had to be a national socialist to post there, or you would be banned. Comb through any archives of that board and you'll see ban messages in every thread with the mods calling anyone to the left of Adolf Hitler a jew. In fact, many libertarians got SUPER angry at 8/pol/'s mods for creating a nazi hugbox and they went to go create /liberty/ for that reason. /leftypol/ was kind of just made for fun when 8chan was new and all sorts of people were coming and going, but it certainly wouldn't have been tolerated for one second on 8/pol/, the so-called "FREEZE PEACH" board.
tl;dr: No, none of this is true, 8chan's /pol/ required posters to be Nazis and so boards like /liberty/ and /leftypol/ were created so people could speak freely, and this poster is just another anon larping as an oldfag like always.
