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 it’s not really a holiday for sharing culture. I don’t know, feel free to correct me if I’m wrong. Adopting black traditions is a touchy topic in the US. Some encourage it, and others decry it as appropriation. Considering that its a holiday commemorating the end of owning black people, I can see how ‘appropriating’ a tradition on that day might be found distasteful.
That said I personally think the concept or cultural appropriation is nonsense. You do not own your culture. That is for everyone. What you own is your own experiences. Those are yours and no one else’s.
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.
