I'm all for it. But there's a decent chance that it's going to be violent.
Are they ready to meet a violent response?
Bikers for Trump tend to have pretty big rallies.
They show up with others of the same mindset and there could easily be a thousand or more attendees.
Numbers like that could be enough to send a message to antifa that their fun won't get them far and they'll scury away, as they've done so many other times when challenged by adults sick of their crap.
........But yeah, things could get sporty.
