I ... say assimilation and greater restriction/regulation of immigration

And around we go again. Some way up thread, I asked you "Do you think it would have been better for England, culturally speaking, if immigration from the West Indies, Pakistan, Bangladesh and Uganda had been severely limited?" You answered "Yes".

Now, if you believe 'mass immigration' has been bad for English culture and should have been limited, you must believe that individual men and women should have been prevented from coming here: there's no other way to limit immigration. And if you think that, then you must think that English culture would be in a better state if those men and women weren't here.

What am I missing? How am I misinterpreting you?
