To address your OP AOG - I would suggest that no-one is against protests against grooming gangs and terrorism.
It's the fact that the 'Democratic Football Lads' Alliance' is the organisation involved.
I am unsure what is 'democratic' about them - but it sounds like a nice legitimising word, even if they probably don't know what it means.
Lads? Seriously? There appear to be a majority who are well over the age of twenty, and are therefore not 'lads' in any sense of the word.
'Football'? What has football got to do with it, apart from the dubious fact that the founder is a football hooligan?
The issue as I see it is this - human nature loves bonding and belonging. There are a large number of young men who enjoy feeling part of a 'brotherhood', united in what on the surface is an admirable cause.
The difficulty is that, so often with these rallies or marches, as with the EDL, BNP, et al, it is almost no time before they revert to a mob mentality like football hooligans.
They like to rush around, pumped full of self-righteous anger and adrenaline, shout at the tops of their voices, and hopefully get to punch a police officer.
That is simple mob hooliganism under the excuse of a righteous cause, hi-jacked by brain-dead numpties who like hitting people and causing mayhem.
The simple fact is, this type of march is utterly counter-productive, because it is the violence that will make the media stories, and the violence that will become the badge of the organisation, whether it actually deserves it, or not.
