What is particularly toxic about this comment though?
I would actually agree that there won't be many poor/minority people participating, but that has more to do with the challenge itself, not the fee. Poor people buy a lot of lottery tickets, particularly when the chance of winning is high. The issue here is that the chances of winning are not high, so the only reason someone would try and go after the prize would be to prove a point, and spending a lot of time and effort to prove a point like this one is a luxury many people don't have.
