Child beauty pageants is a reasonable amount of money. $20bn according to WP. (https://en.wikipedia.org/wiki/Child_beauty_pageant)
There are far worst things happening in the UK though. It's becoming a career decision to neglect your children so you can claim special needs status and therefore disability benefit (and celebrity status on FaceBook amongst peers).
This is a hateful stigmatising lie.
If you want to move the the US, it will take you five years to become a citizen, and another seven before you can run for senate. If you wish to run on a program of abolishing Miss Teen USA (which of course the senate has no power to do), sure, I'll vote for you. But you might find other matters more pressing.
That seems a bit to 'she was asking for it' for my liking.
I dislike the existence of beauty competitions that are aimed at children. Miss Teen USA is aimed at ages 15 to 19.
To me this sounds like you are defending Miss Teen USA, but I know that's not your point. To make your position clear, you should explain why you believe 15-19 year olds are children who are not capable of making the decision to enter a beauty competition.
To be clear: people in that age range are engaging in all sorts of competitions, from sports to academics, and they are given all sorts of responsibilities and privileges such as holding jobs, driving cars, having sex, choosing a career path or course of study, enlisting in the military (or ROTC), etc., so why is this one category of competition/activity so egregious and inappropriate?
It's like if someone were kidnapped in Key West and you wrote "ugh everything is so overpriced there." It's excessively flippant.
