You seem to find it important to stigmatise people for having unprotected sex even in situations where they, by their own understanding, are having protected sex. I’d like you to elaborate a bit more on your philosophy, please! :)

I’m sorry where did they stigmatize people for any sort of sex here?

You can accidentally have unprotected sex by using a condom improperly or using a damaged condom. That’s just a fact with no judgement attached to it. If, after the act, you find out that the condom failed for some reason or if you made the decision to have unprotected sex (again zero judgement, I’m not your dad) plan B is not an irresponsible option for contraception. No stigma
