I'm stunned that you actually thought that I personally share these beliefs.
I believe that the directors (and the daas torah guiding them) believe that.
I believe that they believe that keeping teens on the streets all summer is tantamount to gilui arayos, which is one of the gimel avairos chamuros.
I believe that they believe that the legal or PR risks of opening are nothing compared to the risks of not opening.
I don't know what you personally believe, but I can't believe that any posek is standing behind these principles.
1. The kids are being as used pawns and no rational parent wants to see their kid getting sent home because their camp was shut down by the local Department of Health.
2. If anyone actually believed that this was an issue of gilui arayos the entire community would be funding sending kids from poor homes to summer camp every summer. Even if camps would have opened in a normal (non-Covid) year, there would be many, many kids who would not be in camp due to financial circumstances.
3. The legal/PR risks are nothing compared with the abject chillul Hashem created by a premeditated violation of the law. This is not people not wearing a mask at funeral or not obeying social distance guidelines. These would be organized summer camps choosing to intentionally violate the law.
