bronze players...

It seems like many players in the community has a special view of bronze players. I always see some : "bronzes never admit their mistakes / bronzes means noobs / bronzes means toxicity / etc". (I am not saying it is not the truth - and maybe it is, but it comes from players in silvers / golds who have been bronze in the past.)

Question is : why are bronzes hated by players, that have already been bronzes ? .. Is it the case since the creation of the game ?

Know this : I've played my 10 firsts ranked games recently to be ranked as bronze. I don't ask this because I want to defend the bronze at the cost of my life or whatever, but we all are beginners once and I don't think one of you started the game as gold/plat.
