See I think what you’re doing here is what you accuse the left of doing - conflating conservatives with fascists/far right politics. There is a difference. Spencer is an admitted white supremacist, Milo described a guy with a giant swastika tattoo as ‘very on brand for me’. Those “conservative speakers” being banned from entering countries are usually claiming that multiculturalism equals white genocide and for segregation or expulsion of “lesser” races or cultures. These are not conservative positions.
So which speakers that have been banned from entering countries, banned from social media or violently protested against; are so evil that they cannot be heard?
Is Jordan Peterson far right? What about Ben Shapiro? Dave Rubin? Christina Sommers? Steven Crowder? Lauren Southern? Tommy Robinson? All these guys have been harassed by the left with violent protests, undermining their ability to speak to people who have paid money to see than at a private event or just outright been banned or suspended from social media, simply for having right wing views that the left seems to be wrong.
Yet the left is happy to let people like Louis Farrakhan speak and publically support him, despite his hateful, anti-Semitic, racist vitriol that has actually led to the deaths of people.
I wouldn’t even call Milo far right; he’s just a right wing provocateur who makes his money from saying things the left says nobody should be allowed to say.
And if you don’t dispute that fascists and far right groups are responsible for greater rates of violence, why are you claiming antifa are a worldwide scourge? Wouldn’t that context actually vindicate their position?
Again, you are trying to change the argument. The original question had nothing to do with right wing groups, it was specifically about antifa; but now that you seem to realise that they are indeed a hateful group, so you want to make the question about right wing groups to change the actual argument.
The question was about antifa. No mention was made of anyone else until you realised your error.
