Yeah, the website you linked to was an extreme right propaganda website, aimed at instilling fear and hatred of anyone "swarthy" in the white populous. You can't view articles like that one to get "facts" or to see a view of what's happening. It's agenda driven in the extreme, each article could basically say "these people are different to us, they will kill you and rape your family, we must hound them down and shoot them all in the head". There is absolutely zero worth in linking to, or bothering to read, this racist, reactionary, hate fuelled bullshit.
What's your solution then? That Britain shuts it's borders to anyone who looks a bit "Muslimy"? We ignore our role in World politics/humanity and leave it up to the rest of Europe to help these people because there might be a very small minority who are intent on doing no good? Lets face it, after 7/7 and the Lee Righby killing, it's not as if ISIS/Al Qaeda need to import mental Muslim extremists is it? There's more than enough potential to radicalise the current population, if the individuals are that way inclined.
