Attacking people for that is absolutely not OK, but rejection is a standard part of any artistic process. Absolutely any one (and for that matter, many non-artistic processes at that). Dipping out because you don’t like being rejected doesn’t mean that better skilled people should be penalized. The only way to not be rejected is to keep working and trying.

I’m sympathetic to people who are discouraged. Rejection sucks. But it’s not the fault of frequent winners who are objectively quite good AND are doing their best to provide more resources for the community as a whole so more people can win.
