I have questioned immigration which is NOT racism

You have questioned immigration on what appear to be racist grounds, and then repeatedly - nay, doggedly - refused to do anything to dispel that appearance.

But frankly, after your contemptuous treatment of my last question (that's half an hour of my life I won't get back), I don't feel any need to treat your comments with any more consideration. You're a racist, David; your comments here have made that abundantly clear to most of us, if not, yet, to yourself. I'm not going to engage with you any further.
