I agree with you to a point because I've seen plenty of "adults" who in my mind hide behind the veil of "protecting the kids" when really they're just upset that they have none of these talented kids in their gym.
As for the begging for followers, of course kids are going to do it. It's us as parents that need to make sure we teach our kids to use the internet properly and safely. Begging for followers in my mind is not safe, to many weirdos in this world for me.
I believe there are two very different mentalities when it comes to "celebrity" in general. From my perspective it is normal to admire someone's ability or talents, however, to seek out an autograph or pic with a stranger because, they can act, sing, or do a wicked tumble pass or stunt is a bazaar behavior,
to me. I, personally, want to be able to go to a venue and be able to get from point A to point B without having to fight a crowd of a couple hundred kids wanting an autograph from "Joe" because he is from gym "X", cute, and has amazing toe touches (sarcasm but, let's face it, that's what's happening). These places are crowded, often have narrow hallways and have the sides taped off for teams. There are many little ones at these events that are in risk of being separated from parents, or worse, knocked down and trampled. There are people on crutches, in wheel chairs and elderly. There are special need teams and children where this type of excitement is over stimulating and makes it difficult for them to cope. It is not only the "cheerlebrity" that is at risk of being hurt.
I respect marketing and self expression, however, I also, believe those of us that find it goofy, a potential cost increase, and dangerous deserve the same respect. Take these meet and greets to a different facility where there is room and people have the choice of being part of it.
