That's interesting information SD, thanks. Reading the Snopes article, I don't see that all the claims from the NR article came from this "fake" Antifa manual, but maybe some. Nor do I see that Snopes definitively debunked the manual, only that some things are inconsistent and at least one Antifa person says it is not representative of Antifa thinking, which is apparently not consistent even within the group, which would be expected of Anarchists. So, it does not mean someone involved with Antifa did not create it, but it is certainly is possible someone not involved with them did as well.

Is it reasonable to side with a group like Antifa based solely on the premise that they oppose a group you may also oppose, without vetting their motives or methods? Especially when they are known to be illegally violent, wear masks, are secretive and well organized, and are known to physically attack non-violent conservatives who also oppose the neo-nazis and supremacists? I think not.
