The stupid people are the protesters. They protested in London, and it seems that scuffles broke out. One MP got hit on her way into Parliament. Five or so protesters ran in to the middle of the House of Commons (thus proving again that security there needs to be handled competently, rather than traditionally, although they did apparently have inside help).
Some of the protesters were later interviewed, and there the stupidity revealed itself. Among other things, they excused the violence because they've been protesting to save fox hunting for seven years now, and no-one's paying them attention (everyone say "Awwwwww" now). One person said that these incidents were good, because it's given them world-wide publicity. My snarky reply to the TV was "Yeah, world-wide publicity as IDIOTS".
Further, they fundamentally fail to understand that the rest of the world is (mostly) even less likely to want them to continue fox hunting, and probably can't believe that it wasn't stopped years ago. Most of the people in their own country want it stopped too.
(speaking of "world-wide" - did any of the above make it to non-UK news services ?)
