I can't really remember any WWII veteran ever having anything positive to say about multiculturalism, immigration or diversity. In fact, they all make it quite clear that this isn't what they fought for.   And at the time the US had its own racial segregation and Jim Crow Laws, and Australia had its White Australia Policy, so I don't know how the multicultural lobby manages to interpret WWII as being about defeating racism. They're the ones who've betrayed the values the WWII generation fought for, not us.  We've got every right to use the Battle of Britain as a symbol of what we stand for. Totally true, the dam busters mascot was a black dog called ******, that's pretty dam un-PC!
