I started playing Minecraft by the age of 9 and I sure did say some stupid stuff but I was p mature. Yeah, sure some 9 year olds are pretty dumb *Looks at my 9-year-old lil bro* but they need fun too. You guys should make sure 5-9 year olds not say "kys" or any other stuff that means a bad thing. You should still watch over them.
You're older, not younger, so stop acting like you're the boss. Sometimes children need fun, and so do you. And sure, things do get annoying, but is it their fault? No. They lack knowledge, so why do you not give them the knowledge? And yet, we don't. Sometimes you have to think with your own brain that these children are just starting to count, just starting to learn. Some 9-year-olds are mature, some are not. But sometimes, we all deserve the same thing that kept us happy: Fun.
If you teenagers and adults want to hog Minecraft for your own happiness, I'd rather let them have the fun they deserved. Not all 9-year-olds are annoying, so why can't you just let them have what they want?
I know you might be hating my point of view right now, but please, I beg you, I'm not hating on you guys, I'm just saying that sometimes you have to think before assuming.
No, I'm not defending them, I'm just giving you my point of view.
