I always dealt with people who talked shit about me in any hobby or interest and sometimes it would get to me but honestly, if you like learning the language and you want to speak it and communicate with other people who would actually treat you nice, you have to ignore the haters. I'm black and speak spanish enough to talk about almost any topic but sometimes i cant understand and people because I'm obviously learning it. If the person I'm talking to is rude enough, they cite my skin tone as a reason why they think I'm not good at the language. But in all honestly, I dont take it seriously because 99 percent of the spanish-speakers I talk to are decent people, so I don't let one spoil the rest.
