TL;DR: Nobody is perfecrt.
Edit: I even mispelled "perfect" and left it to show I too am not perfect.
From my knowledge or I think I know ( I don't know, can you repeat the question~ YOU'RE NOT THE BOSS OF ME NOW!!!~~ its a throwback to the U.S tv show, Malcolm in the Middle)
Statistics for players world wide and ranks is as followed:
Bronze:~ 28.4%
Silver:~ 38.75%
Gold:~ 22.64%
Platinum:~ 7.9%
Diamond:~ 1.82%
Masters:~ .04%
Challenger:~ .02%

and to think there are about 32 million gamers now

so technically you can't flame the 28.4% (bronze elo can play with silvers; vice versa) + 3.75% (your elo) + 22.64% (gold elo can play with silvers; vice versa but it's here and there so this is like a variable) = the sum of the total percentage
you then multiply that by roughly 32,000,000 gamers out there who are in the range of Bronze < Silver < Gold ranks and volia!
So you can't blame everyone and except everyone to be challenger cause frankly my buddy it's legit one in .02% players are challenger.
