Didn't you say you were a conservative-libertarian? You sound like you want us to live in 1930s Germany. Maybe you have been sniffing Pelosi's panties too much.
In the EU, and the UK since they didn't change the law after Brexit, it violates people's human rights to be forced to disclose their medical status. Not surprisingly, the UK police get extremely heavy-handed breaking this particular human right. Even the C-19 laws clearly state that you are not required to disclose your exemption for not wearing a mask and/or getting the shot, but the police don't give a fuck.
BTW, if your fellow liberals don't trust the CDC when it suits them, then why should I? They've been quite political over C-19 and they also have extreme TDS, for an org that isn't supposed to be political.
