Over 50% of the country are chavs. There is nothing more stupid in this world than a chav.
I do think that http://www.vox.com/2016/4/21/11451378/smug-american-liberali... this should be mandatory read before declaring a big group of people that won as inferior.
That is the attitude that as well may get Trump elected. And gave Bernie unexpectedly solid run.
If you think that chavs (hey it is totally ok using slurs as long the receiving end is white) are that stupid - why was referendum given in the first place ... chavs may be stupid, but it seems the Conservative and Labor Eton elites are stupider.
Also sophistication for the sake of sophistication is worthless. British lads from underprivileged background may lack some social polish, but the ones I know are awesome people.
