Considering it is an aviation forum, trust most people here will think nothing of it if the ATC chap comes on with a British, Aussie, South Asian, American accent as long as they get their communication correct.
Don't judge a book by it's cover and be comfortable with the accent you have.
Personally I don't think anyone has a personal vendetta with fake accented people 9000 miles away unless the said people are spewing venom against them. I think on the contrary if a person is aping / copying an accent merely due to an overflight of a Blackhawk above his house there are chances he is less of a threat to the US
, than one who is preaching hate in his local language.
