"If you don’t know who he is, you don’t know whether or not he’s credible on any of the issues he discusses."

That's only if he makes a claim that needs backing up. If he made an argument that is free standing on his own then it doesn't. If he said vaccines cause autism, then his credibility would come into play.

"For the record, Murray is well-known for being a right-wing bigot when it comes to Muslims - he wants to restrict immigration based on their religion or perceived religion, and publicly worries about the supposed decline of “white Britons” in London. And any legitimate criticism he might have of the tenets of Islam and how it’s practiced in countries with Sharia law are drowned out by his apparent inability to differentiate between islamists and people who happen to be Muslim.

He believes in “white genocide” and other common tropes of white nationalism, and generally embraces all of the associated conspiracy theories."

Now you are going to have to believe me when I say I have never heard of this guy. Because to me that sounds an interesting point. I have lived in high Muslim areas and I have visited London a lot. I really think this is where the left fall down a lot. People do not want huge amounts of immigration and they especially do not want it from people that cause the decay of the fabric of the city and country rather than integrating. Immigration is and always has been a huge issue to Britains. That is why I think Brexit went through. Also I think because Labour are very bad at talking about immigration but the conservatives are very good at it (though they don't do anything about it) means that the conservatives win more.

I think if the left hand more of an anti-immigration policy they would win more.

Why, from what you have said, is restricting immigration such a terrible thing? London, other cities in the UK, (and a lesser extend the country) have seen huge declines in native population. Again that seems like a valid point. Why are the left not doing anything to address this?
