The quote from Orwell needs to be taken more seriously than May, and I'll assume Kaplan, normally would and apply it to their own views. As it seems they agree that values are universal, they both ignore the Orwellian observation that the 'universal' only applies to their values. May points out that Islam is seemingly bereft of racism (Malcolm X had the same observation). Does that not give Islam some legitimacy in the use of the term 'universal'? Some would say my point is semantic. I don't think so. We, the West, have our beliefs, our values. Isalm, Asia, Sub-Saharan Africa ... wherever you'd like to turn, have theirs.
Orwell's point is apolitical. In fact, it's anti-political.
