To be fair, that is part of how the chans have always been.
Anons have always bickered and argued with each other to some extent. Ego results from intelligence and competitiveness with ego.
Younger mentalities, particularly, are more driven to try and prove their point or receive some amount of validation of their ego - their intellect. Shills and trolls argue for the sake of arguing - so it often becomes hard to figure out who is whom.
Which is where experience comes in. Pick thy battles. Validation from within. Wei wu wei… Wax on, wax off… Etc.
