I guess we're all guilty of it, I just said "American accent" - I should have said "someone who sounds American".
I have a fairly neutral English accent with a twang of the South-West. However, there are multiple accents across England even before Scotland, Wales and Northern Ireland is considered. How many Americans could pick out Bristolian vs Brummie vs Cockney vs Essex vs Home counties vs South West etc etc. I guess most Americans would just chuck them into the British bucket!
