This is not true, I am in America and the name has been seriously problematic.

This is not surprising, the developers were English-speaking Americans who chose a name to cause offense on purpose, in reference to the full-body sex slave suit in Pulp Fiction: https://www.xach.com/gg/1997/1/profile/1/

I don't know who you claim to represent with "the rest of us", but I can only speak for the experience in America. It doesn't matter whether or not you agree with me, it's a simple fact that the name GIMP has been a barrier to its adoption.
