...more than likely trying to justify a way going into the 20/20 election cycle for Antifa to keep sending out invitations to rally's on the right under the direction of saying they realize not everyone can be confrontational but you can come out to support our cause. (If not the exact quote on their site it's close enough, I looked for it but the only thing I found was the fact I spend way to much time on social media sites,...plus if I didn't comment on the article it wouldn't show up in my comment feed) In essence they are saying come prepared to engage in violence if you are able. I am not sure if that was the same article where they were bringing quick dry cement inside milk shake cups and throwing it on people but it wouldn't surprise me after the undercover video's release of the google exec and how they have been working since the 2016 to change the algorithms to ensure a Trump election never happens again that FB would be changing up the rules to entice left wing violence.
