I'm not British so I can't comment directly, but I find it troubling that "leave" supporters are being broadly labeled as racist. Why should UK citizens be forced to allow Brussels to change the demographics of their country?
Before you vote me down, you should know I'be had to change countries twice and have been of the receiving end of some nasty nationalism (mostly in the EU ironically, almost none in the US).
I heard a quote the other day along the lines of "not all those that are voting leave are racists, but all racists are voting leave". Subjectively speaking, I've largely found this to be true.
That's what it sounds like. I mean, if you raised the issue of different rules for shops, vegan ideas, of anything else, then we could think you have issues with actual politics. But you only mentioned the Polish and sausage components. And I since you didn't mention British butcher shops... (same with Russian prostitutes)
So, your argument against charges of racism is that you voted to leave the EU simply because you felt there were too many kielbasa places in London?!? Kind of an overreaction, don't you think?
