So why do you suppose he baited eleven thousand people into a venue and then stood them up and sent them into the street? So they could all enjoy a nice walk down Michigan Avenue?
The protestor imbeciles caused the cancellation, AS YOU KNOW.
Actually I "know" no such thing, and neither do you. Here's the thing --- wishful revisionist thinking is not the same as "knowing".
What I actually DO know is what the security authorities have already reported, and which I've posted a dozen times to you Denialists. The corollary to the above rule is that simple Denialism doesn't make the factual history go away. Nothing can do that. You'll just have to accept it.
And you'll also have to come to grips that whatever wacko websites are feeding you this horseshit are lying to you, and that that's easily debunked. Not a position I'd want to be in.
The protestors do not have "their own rally". They came to have a voice in the one that was relevant to them.
And again ----- no one in any security or police capacity suggested there were security concerns. Rump completely pulled that out of his own ass, for the purpose of trying to play the victim card
Oh no. No security concerns.

And that's why the Chicago police ARRESTED 5 people ? Which there would have been many more if the mayor hadn't told the police to not arrest anyone.

Five arrests and a couple of minor injuries isn't anywhere near a security concern when you have tens of thousands of people in one spontaneous unorganized place. And that was
after Rump released ten thousand unsatiated hordes into the streets all at once.
Obviously this one didn't generate the ROI he must have had in mind.
But he should be used to that by now, even if he does address them all with self-delusion.
