I mostly agree - these marches are usually sort of tribal affairs where both sides go for a ruck (though the anti side defensively). The amount of football 'hooligans' that attend on the 'right' side ensures it'll get a bit punchy. I'm for non-violence in general, but as shambles said defending victims is different.
It's difficult, because I agree in freedom to hold whatever ideas you want (outside of incitement etc) and treating people equally under the law; but i think at the least i want to recognise the difference between radical left and radical right wing politics - to me the radical right seems inherently violent (i'm thinking more golden dawn/svoboda/NF than edl), while the radical left sometimes uses violence, not from principle but as a means to an equitable end, however misguided in practice. The right's equitable end, usually only happens when some outgroup has been got rid of.
Do you not think that maybe the two groups propensity to violence can be attributed (at least in part) to the fact that most of it, left or right, is perpetrated by angry young males who are full of piss and vinegar, as most militant 'politicised' types of any persuasion tend to be?
I don't know if you've been involved with, or on the fringes of, hard left or right politics, but if you have then you'll know that it's an extremely macho domain; almost exclusively the preserve of males, most of them young. They may even believe strongly in their respective ideologies, and as you point out, it's easier to sympathise with the leftists in that respect. But very often their idealism stems from, or is fuelled by, anger and frustration which makes violence inevitable, even desirable.
As for the 'provocative' locations chosen for demonstrations, these locations are the ones with the most racial tension, so of course far right groups will target them. It's exploitative and disruptive, for sure, but it's no different to how the three major political parties approach campaigns. It's how politics works. In any case, if the presence of one group is considered inflammatory, does it not follow that a counter-demonstration ups the ante somewhat?
I had friends who attended the Oldham riots in 'protest' at the presence of far-right elements, and they'd be the first to admit that their presence did more to aggravate tensions than it did to ease them. The left-wing groups were there with their own agenda, not to 'protect' the local Asian population, who (from what I've gathered from talking to some of those affected) didn't want them there anyway because they rightly saw them as adding to the problem. The same has happened with some EDL demonstrations which started out as pathetic damp squibs until UAF and friends lit the blue torch paper.
There's a lot of dangerous idiocy on both sides, and while I'm not ashamed to admit that I'd rather have a pint with the guys from UAF than I would their counterparts in the EDL, I wouldn't rush to be an apologist for one bunch of thugs over the other.
