Excellent post. Forcing views underground lends them a form of credibility - 'they are scared of the truth'.They are probably using online game chat firstly because it is secure and private, and secondly because there is nowhere on the web where one!can freely engage in these issues.
If a newbie Adolf appeared on Arrse, most of us would like to engage with him to point out that, actually, murdering 10 million civilians (a quarter of whom were little kids) is a shîtty way to behave, and not the best way to win new friends.
However this will never happen, because newbie Adolf will be banned after his first post, as he will on every other forum on the web.
This makes the site owners appear very virtuous (and they are, having spent a week in the Med. with GCO, rubbing sunlotion into his back under threat of keelhauling), but.... it forces these warped individuals underground where they won’t be challenged and can foster new blood).
No matter the reason, political censorship never works. It didn’t work in Nazi Germany in Soviet Russia and it won’t work in the UK. It makes the government look good in the very short term, but inevitably fosters dissent and even hatred.
All political views, no matter how distasteful, should be on open view, so they can be dissected and ridiculed if necessary. That’s the only way these idiots will get to gauge the hostility they engender.
To use a non-XRW example, the way the mainstream news and social media suppressed the Hunter Biden laptop story has allowed serious commentators (Douglas Murray for example) to speculate that, had voters known the truth, Biden might not have won. The allegations may have been rubbish but they were not tested and have gained credibility from that.
Suppression of debate doesn't work and while I am not an expert on the XRW I would speculate that it is gaining traction because some people are resentful of their views being ignored, while other views are pushed at them. And the propaganda material for recruiters is in plain view - 'white people are banned from applying for some jobs' ; 'Let's talk about white guilt/privilege', plus the more obvious issues.
Add that to the mix with younger people who may feel they have no future prospects - and recruiters will make generalisations based on one news story - 'People won't give you a job mate; you're the wrong colour' - and some people will be attracted to the XRW (or, with arguments made from a different direction, attracted to Jihadism).
It is similar to the situation in Ulster on the eve of the troubles: if society writes off people because of things they can't control (their religion, colour, where they live) it will lead to trouble.
