Oh dear, the old chestnut. Let's quote statistics to validate a point.
Except that, the statistics quoted are not worth a carrot. 3,000 people polled. Yeah, that's statistically valid. Some people never seem to grasp a basic understanding of how to advance a valid premise. And asking 3,000 people out of the whole population of the UK is like asking 10 people on the Gwladys Street a question, and then advancing that those views are those of the total Everton-supporting population!
OF COURSE, a certain %age of the population think that immigration should be controlled. The reasons why have been gone over again and again and again in this thread in the months past, and I'm not going to repeat them again here.
OF COURSE, there are a whole raft of other issues why people voted to leave, but the likes of you, Foot Long, and some others, are not interested in those - you simply push the immigration button time and time and time again. Boring...
