I think any sort of generalisations are dangerous, Comments like "All Irish are drunks" get people offended, so to tar all sort of political or environmental protest under the one brush is equally as offensive. I agree with political protest but just not inside a football match. I think it is very easy to throw around comments like tree huggers about people but hopefully you wont have to make a protest someday. Students, Nurses, Farmers etc all protest and all have the right to protest and to be honest I think that is a good thing, whether I agree with their view or not but the right to protest is part of any democracy.
