I'm not sure that conflating this particular issue with the matter of cultural diversity in general is helpful... I would like to think we are a little more sophisticated and a little better able to identify what matters and what does not matter.
But what has happened is that we have been pushed in a direction that ALL cultural diversity is a good thing. That's been combined with a relentless attack on any aspect of Britishness (for want of a better word) to the point where we no longer have any reasonable definition for it, let alone feel comfortable demonstrating it without there being negative connotations. The ownership of a St George's flag was, until very recently, the mark of a member of the National Front or BNP, not the mark of a patriot. In the minds of many it still is grounds for suspicion.
^Condoning sexism (whether rooted in extremist religoin or not) = bad.
Condemning all multiculturalism = just as bad.^
Is it? What is multiculturalism? What it means is not us all mixing and getting along together, but ghettoisation. It's a pernicious ideology whose damaging effects only appear as decades pass. Why can't we say that a failure to adopt the mores, culture and language of the place where you live is a problem?
Most of us, whether on the left or the right politically, have the ability to distinguish right from wrong without making sweeping statements. Are you advocating that we should believe that all Western cultural values are better than all other cultural values, flatpack? Because that really would be a hiding to nowhere.
No. But we should be able to stand up and say "These values - such as the ones where we don't separate women off and treat them as second class citizens - are better than yours, they are non-negotiable, and if you don't like them then tough." And our political classes can't, because they're so uncertain about what they stand for or what country or society they're representing that they have no sense of why it matters to say 'no' to segregation in universities.
