You are correct Greta. My apology.
You are asking if I can see the connection between the leave vote as a protest against the EU, well yes I can see that it would have played a great part in the 17.5million voting leave, along with other reasons. The connection you are attempting to make is of course: the "message" of the day, being that leave voters are from deprived area's and voted against the EU instead of the blaming the Government, if I have read your comments correctly.
One of the ways I can address this is to first ask you to consider that there were two votes: the referendum and the General Election. The referendum, majority voted leave, the General Election the Government and Opposition party's both stood on a pro Brexit mandate. This would indicate that the majority of people in the UK wish to leave the EU, having been presented with a cross party vote and then a party political vote with a Brexit option and then a Brexit mandate in the two main political party's. The sensible answer is to say that there would have been a wide variety of mixed reason's why people voted both remain and leave, and in the General Election the two main pro Brexit party's both got in to Parliament, as Government and Opposition..
One thing that comes to mind of course is that you might be saying, since your post is supporting Alexa's post, that leave voters are deprived and living in industrial wastelands, not the exact words used by Alexa but the essence is there. If Alexa and Varian are right, they are telling me that 17.5 million voters are living in industrial wastelands, and are unemployed, uneducated and living on "handouts" as your friend's Alexa and Varian claimed in separate post's. Then a different group or the same group of voters plus others, then voted for both the Conservative and Labour Party's at the General Election which would be the total of all who voted for both Party's, the figures I could look up, but feel it is unnecessary since the point is made I think.
