PSA To People In Bronze; We don't know anything

This is a bit of a vent post but it absolutely grinds my gears when I'm playing Ranked and people in champion select are saying stuff like, "man we have full AD comp gg" "wow where's all our ad" "pick x champion dood its good trust me", and in game when someone who's super behind tries to make shot calls "gank me press r" "baron(when there are still 5 people on the enemy team)" "go in omg team"

You know as much as I do dude. I realize some people who say that have good intentions but a lot of it comes off as condescending. If you're giving bad advice and later say things such as "team didn't listen gg" then you have every right to still be in Bronze.
