It’s only criminal if it is against the law...but that goes without saying.
However, @ButterflyKiss, this is not terrorizing, this is manipulating. The protesters simply removed these manipulations from their line and nothing terrorizing happened. It is when protesters sit ideally by or join in on the rock throwing that they are "terrorized." If they are dumb enough to be targeted with negative advertisement, so be it.

Either way, this is wrong. A message should remain free from obstruction (Even if that has never happened.) However, it is up to the actual protestors to dictate how clean and clear their message is--and to defend their message from outsiders.

Making fun of somebody because they're overweight is kinda slimy =(

...but making fun of somebody because they're stupid? clean and clear...

If she came out talkin' about some discovery of a gene linked to cancer or a mathematical theorem linking everything in the universe together, I'm sure the fat thing wouldn't be an issue.
