Perhaps we can use animal rights protests in the UK. These started off by increasing welfare for farm animals; reducing use of animal testing in cosmetics; reducing the amount of fur sold in department stores. But then other changes included tighter controls on what demonstrations could do and now UK government is hardline on supporting vivisection and denying rights to (even peacefully) protest such.
I would say something where people organise an event and bring placards rather than outright terrorism.
The difference is probably that a majority of people don't support the fur trade but most people support animal testing for medical research and it's unlikely that any form of protest would really change public opinion.
