Does it bother anyone when folks say "Murica", or "Merica" instead of America?

Yes it does. Our country is America or the United States.

Unless it's someone from another country. If you live in this country say it correct or I'll be glad to help you!

It’s more often due to a heavy accent than disrespect!!!! I’m not very tolerant in many areas, but I honestly believe that most mean no ill intent. To me….if you are legally in this country (different subject matter) than welcome, because you came here the right way. Therefore, if you did not break the law coming here, you just might obey all U.S. laws. It’s a little bit apples and oranges here, so to be more clear is does not generally upset me, as I know that some foreign accents are hard to lose and often requires speech therapy to remove.

Must be an age thing. Never heard it.
