The solution to covid/flu is wearing well-fitting masks and vaccines rather than never getting out.

The solution to STIs is good protection with vaccines, condoms and tests.

Religion can stay out of that.

Yeah that’s a moral crusade. It’s a public health issue; you deal with it through public health measures like education, vaccination, and treatment. You don’t make it go away by wagging your finger at it.
