If you want to denegrate an eintire fiath / culture / nation / organisation etc. it is really easy to do.
Simply pick out the extreme behaviour of apparent members of the faith / culture etc, and use it to foster the idea that this is the behaviour of all such individuals.
If you extrapolate that argument, you come up with the EDL stance - some Muslims groom young girls for sex - therefore all Muslim men are sexual predators and they should be exported, preferable after castration.
It is standard scare tactics, it works on uneducated ill-informed fearful minds, and it is fundamentally wrong.
If the EDl want a target for religious evil - why don't they look a little closer to home - every Catholic priest is a child-abusing sodmite? Why? because a minority are convicted as such, so it must be all of them.
But taking a stance against native white religion may not prove quite such an easy target, even though it is every bit as valid, if hate-stirring is what gets you through the day.
Self-rigteousness is a very very dangerous concept, and it's a cornerstone of the EDL.
