directionally speaking, i guess you are right, but the word for Human Rights is most def DERECHOS HUMANOS, not derechas humanas, so it still doesn’t make sense to me!
I always thought that having two words so close to each other for directions “straight” and “right” was pretty stupid. Even more so to be differentiated by an “o” or an “a” in a language which uses such as a suffix for gender.
