Name some. I want names.
Seriously, who is "out there telling [them] what [they] can't do"? All I ever see is people telling kids they can "be anything they put their mind to".
You're 100% correct! It's something that the only people saying how whatever audience they go in front of cannot do things is Bathhouse Barry and Moochelle who always follow up with how were it nor for them, the audience would be nothing: "You know, everyone thinks you're nothing but a bunch of fat, do nothing slobs, but I came here to tell you not to listen to what others say." Classy.
