Why do we judge others over different Islamic opinions?

Salam, I feel really worn out seeing all these different takes on matters like music, drawing, wearing the hijab, singing, or women traveling alone. Islam encourages respectful discussion among believers, which is wonderful, but why do we sometimes attack and intimidate those who, for example, listen to music or draw living beings when there are legitimate scholarly opinions that say it's permissible? It sometimes makes me wonder: is faith just a matter of luck, where you hope your understanding is the right one? Let's remember to be kind and seek knowledge together, insha'Allah.
