It's their right to object and I don't deny them that. I went on a (non related) protest about 3 years after leaving and it's quite interesting the way that otherwise normal members of society get very threatened by it.
Handing out leaflets, a car slowed and the window came down, I bent forward and received the full contents of his throat full in the face. People shouting C**t, nutters etc.
In an odd way it was quite fun, I can see why people who do it get excited by it.
