I agree with Alito on his "the state treated houses of worship less favorably than it did casinos" point, and I don't think it's anti-science to say that.

To quote NYT: "Casinos were limited to 50 percent of their fire-code capacities, while houses of worship were subject to a flat 50-person limit."

It seems reasonable to me that both should be limited to a 50-person limit, or perhaps a people-per-area limit (although I do understand that Churches are higher risk because singing spreads the virus much more than silently sitting at a slot machine).
