"been telling people who voted leave that they should not have done so, that their vote was wrong, irresponsible, reckless, xenophobic, ill informed, selfish etc, etc. "
Go look at the thread about remainers being condescending towards leavers, and look at the reasons laid out for leaving
They tick all of those boxes you laid up above. In fact, although I just delurked the other day, here and in other places what you find is that these views are challenged and remainers accused of bullying, sneering etc. Then people leave, and the little leaver groups just start repeating the same incorrect, ill informed, xenophobic rubbish. I'll list them below and outline why they are what you claim they are not.
School places are short because of immigrants. Not true.
The NHS is under pressure because of immigrants. Not True.
Immigration drives down wages. Not True.
All three of these are brilliant examples of being ill informed and xenophobic, one because the counter information is widely available, and two because when this is available still blaming immigrants shows a huge amount of prejudice.
Just a start, if you want me to shoot down the democracy arguments too its fairly easy, or those about our net contributions.
Even if you disagree with all of the above and for what ever reason want out of the EU, you aligned yourself with the uninformed, xenophobic bigots in order to win. For shame.
