Why shouldn't it? Julien Blanc is not a UK citizen, he's an alien national who wishes to do business in the UK by teaching his methods there. Entering the country is a privilege, not a right.
Entering the country is a privilege
Check your privilege! XD
Sorry, I couldn't resist.
Anyway, yes, a government has the sovereign right to deny foreign citizens the possibility to enter the country, but it needs legal basis to do so. It's not like any random clerk at the visa office can turn you back because they don't like your face.
I don't know what legal justification they used to keep Julien Blanc out, but given the type of people that the UK has let in its territory, I guess it was probably quite unusual.
Through LessWrong, I've discovered the no-reactionary movement. Servery says that there are some of you here.
I'm curious, what lead you to accept the basic premises of the movement? What is the story of your personal "conversion"? Was there some particular insight or information that was important in convincing you? Was it something that just "clicked" for you or that you had always felt in a vague way? Were any of you "raised in it"?
Feel free to forward my questions to others or direct me towards a better forum for asking this.
I hope that this is in no way demeaning or insulting. I'm genuinely curious and my questioning is value free. If you point me towards compelling evidence of the neo-reactionary premise, I'll update on it.
