Since I've seen so many posts here on "hurr durr white people can't have dreads because it's appropriating black culture", I thought I'd post my own personal opinions, in a feminist-friendly way. Please keep in mind that I'm not very articulate and sometimes I have trouble turning my thoughts into words.
1. "White people can wear dreads but a black person would have to cut them off for a job!" -- Both people would, if the job's anything more than a customer service job. In the work place, there's supposed to be a sense of professionalism and because people have a generally negative opinion of dreads (they're dirty, unkempt, et.), managers/owners wouldn't want to hire said person. I'm asked to cover up my tattoos while I'm on the job. It's not the same as asking someone to cut their hair, but they both fall in line with the whole professionalism appearance you're supposed to have.
2. "It's appropriating black culture!" -- Firstly, there's no such thing as "black culture". There's Jamaican culture, for example, and Kenyan culture. The two might have overlapping themes/ideals (I don't know enough about either culture to make a Venn diagram) but they're completely separate cultures. I know this because of the countries' geographical locations. Languages, cultures, and religions vary between locations. Find me an actual culture in which dreads play an actual role.
3. "It's so cool and trendy for a white person to have dreads but..." -- I'm not even going to finish typing this sentence because it's so stupid. A white person looks stupid with dreads. A black person looks stupid with dreads. Anyone looks stupid with dreads.
4. "Black people have had dreads for hundreds of years." -- Ancient Romans, Greeks, and Egyptians (who, by looking at their geographical locations, were tan- or brown-skinned, not black) have been discovered to have had dreads as well. Possibly for longer than this mysterious "black culture" has. I wouldn't say for sure, because I'm not a historian, but they did have dreads.
Now, I'll add the part I call "feminists/SJWs play cards I've heard before".
1. "Lol whiteys like you wouldn't understand." -- I'm not white. My father was born and raised in Mexico. I'm pale, but I'm not white. A person's skin color doesn't discredit their opinion.
2. "Shut the fuck up, you're anti-feminist." -- Whether or not I identify as a feminist is neither here nor there, having dreads is not cultural appropriation.
