It wasn't irrational numbnuts.
I WAS a supporter of the EU, until I became interested in how the system they had worked, where it was heading, what it was planning, how they regarded the United Kingdom and it's citizens, and what future they saw for the EU and it's place in the world.
I am a child of the EU, born in it, grew up in it, taught to respect it and to love it, and knew nothing before it. So all talk of Empire, Rule Britannia and other bullshit is wasted on me. I am of the generation that saw the EU for what it was, not indoctrinated to continue to believe there was nothing better, like you. I don't care about Farage or his campaigners, I never did. My decision was based on my own personal opinion of what the EU was striving towards, from their own mouths and their own words. And I didn't like it.
And you cannot fathom that, can you. That someone who was once supportive of the EU turned against it from their own opinion. No wonder your "side" keeps losing every major political debate. You refuse to accept that not everyone is a sheep like you and should just "accept" the EU as infallible.
