Camp Agudah is run by Rabbi Belsky Shlit”a, which is why it was mentioned, as it’s run kehalacha.
As my rav said about the Lipa ban, if you ban it they’ll go to worse. Same here. If you’re on the madreiga to appreciate the fact that it’s not as hartzig and Jewish as other music, gezunteheit. You have every right to be machmir, and ashrecha for your spiritual refinement. However, the “amcha” isn’t holding by this and trying to force it on them will be a kilkul as we already saw with the Lipa ban.
