There have been plenty of studies done with / in regards of masks.
Also I'm totally lost on why you would ever rant on masks. They are easy to wear and do relatively good in comparison to the effort of wearing one.
I also find it tremendously shitty to write this in a way that it was always clear from the beginning how this new Virus would interact with us.
Why people like you think it's reasonable at all NOT TO BE careful for a totally NEW UnKNOWN airborne virus?
This is srsly your first response to a unknown new thread? Ignoring it?
And the situation at the beginning with alpha then beta and then delta was constantly changing.
And I really hope you are at least as opiniated about all the other scams and not just your 'covid scam' like homeopathic 'medicin' and other things like religion.
