I have been to animal circuses before and i wasnt against them just thought the cat enclosures could of been bigger.
Its quite intimadating with all the protesters espcially last time i went because i knew some of them lol.
That's the way that they operate. Unable to sustain a discussion based on fact, they attempt to intimidate people and brow beat them into their way of thinking.
Fortunately, in a democracy, the will of the majority ultimately prevails.
If you go, and decide that you don't want to go again, that is your right.
But these people don't have the right to stop you from going in the first place.
