wrong you move around these threads always saying people need to 'understand' each other
Blimey, you make it sound like I'm doing something wrong by posting on different threads and by suggesting that people try to understand other's point of view....and are you following me??? 
but what you are spectactularly failing to grasp is that, in order to 'understand' someone you have to get to the bottom of their reasoning for their choices
Well, no, you have to do your best to try to understand their reasoning and choices, but none of us can completely understand each other. It is your responsibility to try to understand, with good faith, as well as for the other person to explain. And I could answer your big long list of q's and you would say my answers do not stand up to scrutiny, are wrong according to the evidence, etc, etc. But just to take one, the EU and UK migrants issue, as I have said before, I would like to see the gov unilaterally guarantee EU nationals' rights. However, I would have like to see the EU agree a reciprocal deal, but sadly Angela Merkel scuppered this. There are some down sides to leaving the EU. Any major change will have negative consequences. I think the way the EU is dealing with this issue is absolutely par for the course, and a demonstration of why we need to leave now, before we are yet further entangled.
