Yes, he could be--and a lot of this is a fine mess of his own making. He's positioned himself in such a way relative to Pride that, at this rate, it's hard not to discount the possibility of him being the target of assassination or some such attack on his person. Really. It isn't that he's paranoid about, uh, "faggots" because they're "faggots" (something which can be overcome, cf. Mel Lastman, 1997); he's paranoid that some of them may be out for his scalp. Not his penis. His scalp. And not because they're "faggots". Because they're angry. And as for Ford, he isn't a Trudeau at St Jean Baptiste in 1968, that's for sure.
Mel Lastman wasn't toxic. Rob Ford is. If you think Ford doing the parade is all going to be pleasant sailing, happy happy, joy joy, hiya mayor and all that, you've got another think coming. Even if there isn't an attempt on his life, expect the likelihood of ugly.
That said, I'm not discouraging him from going. But whatever happens...I'm fatalistic about it.
