"Como poeta, me gustaría decir que mi único argumento es con aquellos que no me interesan, y que no puedo tener disputa con aquellos que sí me interesan."

Simplified Meaning:

When someone says they only have an argument with people who don't interest them, they're suggesting that they find no reason to fight or disagree with people they find intriguing or engaging. Instead, they feel more confrontational towards those they find dull or uninteresting. Imagine you are in a classroom, and you have classmates who are very different from you in terms of hobbies and views. If someone shares something in class that you are curious about, even if you disagree, you're likely to listen and discuss calmly because you're interested in learning more. But if someone talks about something that completely bores you, you might get frustrated easily and argue just because you don't care about what they're saying. To put this into a real-life perspective, think about how you feel towards friends versus strangers. With friends, even if they do something wrong or you don’t see eye to eye, there’s a desire to understand them because they matter to you. Conversely, a stranger on the internet making an uninformed comment might quickly irritate you, leading to a heated debate. This quote suggests focusing your energy on engaging meaningfully with people who stimulate your mind and ignoring unnecessary disputes with those who don’t catch your interest. In short, it’s wiser and more fulfilling to invest in relationships and discussions that truly matter to you.
