You are buying the rhetoric about all protestors being of a certain ilk.
Were the protestors in the 400,000 strong Countryside Alliance march in 2002, all van dwelling crusties, all anarchists, all left wing agitators hell bent on destroying the country. No they weren't because the then leader of HM Opposition, a certain Ian Duncan Smith was one of the protestors on that march, as were such luminaries like Vinny Jones and Rory Bremner.
74% of the people thought at the time that Fox Hunting should be banned, but the protest went ahead and I supported there right to protest, because I am a democrat who believes in the right to protest as being a central tenet of democracy.
What we are seeing once again is the demonisation of the working class right to protest, the middle class protests are fine as I have shown, but working class protests are met with hostility and media denigration.
