We do know something about you - you're THICK. Which part of infringement of copyright and trademark don't you get ?? Yes the club could sue but who exactly do they sue ?
But they HAVE done something wrong - they have used a copyright and a trademark without permission for a purpose for which wasn't intended. Of course they can fly the Albion flag but they can't use it to imply that the club support EDL - that is what they have done.
If you really don't support...
Although it's usually useful to have a basic grasp of your mother tongue if you want to put forward an argument people can understand. I wouldn't dismiss them as fascist - more like racist.
