People who call others "sheep" for what they believe - and especially for believing the widespread advice of experts - are often the least educated, least intelligent people. They tend to have a total lack of expertise, live in an echo chamber and latch onto any snake oil salesman who let's them believe what they wanted to believe from the start.
Like, for example, here are
40 different studies, peer reviewed and published in medical journals, all coming to the same conclusion FOR the use of masks. On the other side of the table is a fitness tester with a 2 year degree from community college & a doctor who literally believes demons watch you when you whack off.
Only reason you'd side with demon sperm lady and masks make you hypoxic guy? They're telling you what you want to hear.
