Disclaimer: I am not trolling, I am an autistic person who doesn’t understand so many social nuances. Also I am from New Hampshire (97% white), so I just don’t have any close African-American friends that I am willing to risk asking such a loaded question.
I think that is especially true in the United States where sharing cultures is so central to the nation’s identity. I think it really comes down to intent. As long as you aren’t doing something in a mocking or condescending way, I don’t think any reasonable person would be offended.
I know this is a little different due to the power dynamic (America being a powerful country) but people around the world love wearing random American stuff like baseball jerseys or whatever. Saw a lot of it in Europe. Probably theres no profound reason behind it, they just like the style. I think it’s cool, I’m not mad that they don’t really know who the Texas Rangers are or whatever.
