People should be concerned about this issue and pay close attention. But there is very little reason to be very concerned at all. These mask mandates, or even requiring vaccine proof, is not a cover story for a take over of the U.S.
These are extremely rational and justified, and even mild, measures being taken to address a very real and easily verified threat.
The U.S. is not Australia. No one's first amendment rights are being curtailed. Anything anyone wants to say is perfectly accessible to the public. No one is being fined.
And the U.S. is not China or a a banana republic and there's absolutely no evidence that we're in any danger of becoming like either.
No, the West isn't find. Mild tyranny isn't cool and how temporary these measures are is debated. If they actually were temporary, why is there no restriction for how long they can last? How much longer will it go? Nobody knows.
This is a loophole in our constitutions, they can use "emergency" situations to suspend civil rights indefinitely. This very same method has been used many times in history to establish dictatorships and totalitarian systems, so it's a very legitimate concern.
