'Multiculturalism' and meta-ethical subjective relativism

Please have a look at the post with this title on Barefoot Bum's blog. He launches a scathing personal attack on me which completely misrepresents my views.

I haven't time to deal with this before going on holiday in a couple of hours. I may - or may not - reply at length when I return. Meanwhile, I'll be grateful for any comments others may feel inclined to place on BB's site.
