i agree with that. as a young person i had a number of strong opinions. i am still kicking myself for insisting that a mailinglist server written in C would be better than one in python, based on the language alone. my opinion was just blind prejudice despite not being strong in C, and always having preferred languages like pike, python or javascript.

basically most strong opinions are based on lack of knowledge. one that i have now for example is that kubernetes is over engineered for most problems. it's based on discussions here on HN and not any actual knowledge or experience with it.

as a consequence i have learned to be very careful with strongly expressing opinions, because it can be difficult to back them up, especially when i face someone more knowledgeable in that space.
