in my defence, I've had to criticise you for your lack of ability to analyse such matters clearly, which formal study can improve our ability at

Don't make me laugh. I've got a doctorate and I think your arguments are shallow, confused and deluded. I've seen no lack of ability in IB's comments, merely an entirely commendable persistence in disagreeing with you.

there IS a difference between questioning immigration and being racist; and I've only repeatedly questioned the act of immigration itself

There is a difference between being racist and questioning immigration for economic reasons, say, or for political reasons. But, as several of us have repeatedly pointed out, you question immigration on racial grounds. You want fewer people with the wrong kind of suntan to be allowed entry to England's green and pleasant land. It doesn't take a degree to work out that that's a racist attitude.
