I would like to take up the point made by some poster upthread, "if you do not like it here then leave" to which many responded, in measurable and articulate way, that this is not possible practically.
I see that remark differently. I see it as typical of a group of people who believe they can speak for the whole country and, if they win, their preferred method of silencing the opposition is... getting rid of it.
This was the modus operandi of Mussolini's fascist regime. You do not like Fascism? Well, we have won, we are the will of the true Italian people so you are not obviously welcome here. You are not a true Italian. And writes, journalists, teachers were literally sent away or interned in far islands.
Whenever there is an opposition and somebody tells them to emigrate if you don't like it call them out on this as a far-right strategy because this is what it is. Don't engage with them on the practical level, but call them our oh their right to define themselves as more British then you, more patriotic then you.
I am a patriot and my patriotism expresses through making this country wealthier, happier and more inclusive. To me this means more European. If you think differently, fine, but do not try to exile me or do not for one minute think you can speak for the whole country and make me feel an outsider. I also speak for a group and we have the same right as you have to be here and to change the country, with democratic means, as we see fit.
