Irregular reminder for junior engineers:
You absolutely SHOULD argue with random people on the internet.
People who tell you that flamewars are useless, do it after they spent significant time participating in them.
And yes, generic flamewars indeed *become* useless over time once you learn the main arguments and the rules of the game.
You absolutely should learn those rules though. And no one will teach you that in the university.
Do remember that it is a sparring, not a fight. And enjoy.
