Controversial views (britain First)

I'm always a little disappointed when I see people that I admire and respect liking posts like the ones below.  Maybe it's me, maybe I'm wrong but I don't understand the justification for 'liking' this.

Don't get me wrong, it's their choice and I respect that, my issues with it are as follows:

1.)  We don't have the facts.  We don't know what was said, why or how so how can we judge.  Irrespective of that I am exactly the sort of person who would argue with a member of the police if I thought they were wrong.  Do I deserve a knife pointed at me for that ?

2.) Innocent until proven guilty.  A knife is a lethal weapon.  What situation justifies that against an unarmed person ?

3.) The police are trained to deal with confrontation, they deal with it day in and day out.  They have self defence training, backup as well as possibly/likely chemical spray/baton/knife did he need hostile assistance against an unarmed civilian ?

4.) The issue was resolved without issue but now it's made the front page of many newspapers.  Was it newsworthy ?  It shouldn't have been.

5.) The guy allegedly argued for 5 minutes.  Given the quantity of police and guards in the area, surely this could have been handled in a more political manner much more swiftly than it was.

6.) When a group/sites such as 'infidel defence league' presents this it seems to take on a possibly unjustified racial aspect which may not have been there at all.

Maybe the guy was in the wrong.  I'm not arguing that, I'm arguing that the masses should not rush to judgement without being fully informed of the facts.  By showing your approval with a 'like' you are endorsing bayonets in peoples faces for arguing/shouting as the British way.  Given that Britain is massively multicultural and I have many friends of many ethnicities I'd like to think that race wasn't the provocation for this situation.

There are racial things that I do not approve of such as Shariah law, Niqab and Burka but they have nothing to do with race and more to do with sexual equality, social and political reasons.

Please feel free to comment, I'm happy to take constructive criticism.  Any offensive comments and/or vulgarity will not be published.
