Well you can't expect most people of English heritage to understand the particular of french political correctness.
The gap is just to huge , the irreverence of french satirical newspaper is beyond most of the english word capacity to accept.
Do UK/US people do even like really dark humour anyway ?
Not offended by said cartoons, and perfectly capable of seeing the satire.
Of course, if you judge English people by by the English media, that would be understandable, and if by English 'heritage' you don't actually mean English people, then maybe that's why they're no longer here.
Sure, the English 'ideology' has unfortunately succumbed to far more political correctness over the years, but I'd suggest that most of us can appreciate irreverence far beyond that which may be perceived.
