Nothing. Nothing is bad about that. The beautiful thing about language is that nobody owns it. You could walk around using 1/4 french, english, spanish and swahili and there would be nothing wrong with it. -My hat would be off to you for being so lingual! I'm 1/2 mexican, does that mean I get to use half spanish words when speaking? It's all absurd. I think people both positively and negatively ascribe too much identity with race/ethnicity. I'm proud to be ____ -with the blank being filled with southern, eastern, northern, western, brown, black, white, christian, muslim, buddhist, female, male, tv/ts, tall, short, american.... whatever. Just be proud of YOU, if you're someone worth being proud of. It's your efforts in life that ascribe meaning to you, not these other things, imo. Anyways, yeah... you don't need a certain level of pigment or need to be from a hispanic cultural background in order to employ spanish words in your speech. Está todo bien!
