@hansw I think there is a big diffrence between checking if someone is actively infections at the moment vs demanding verification as to whether someone too a medication against their will to be accepted into soceity.
I should point out that I'd argue that while screen to get in is ok I would oppose any recording of the screening data.. it would have to be done without records being taken and the identity of the person remain anonymous to protect their medical information. But yes if it can be shown you are actively shedding a virus I dont mind you being rejected from entry, but Id be opposed to saying "you must consume this drug to enter this building". To me it is clear why these are different things.
