Nobody is saying that.
however, 1. The point is creepy has form for setting this sort of thing up, & 2. The activists got a "tip-off" about where creepy would be appearing, as did the press who had already written their stories.
Regardless, lets look at the actual story here - creepy goes about shouting in public, three guys shout back, which has happened many times before, but somehow this time it's a "violent mob". And you don't think there was a plan here?
Put another way, you don't think Izzard dressing up as a wifie and then going walkies in Glasgow wasn't done deliberately as they thought they'd get some sort of homo-phobic abuse that they could peddle? When that failed to transpire they had to run with "violent", even though there was no suggestion of that whatsoever?
