Masks are gags, basically, to muzzle people into silence. They are deeply sinister and all the more so because they are justified on the basis of consideration for others.
Lol, sorry, but I think a lot of the people on this thread are a little too paranoid.
Just because you're paranoid doesn't mean they're not out to get you.
Out to get you by making you wear half a mask? 
Sorry, but as much as I agree with most of you in other areas I can't agree here.
You don't have to agree.
Time will tell.

Quite true. But if people start making martyrs of themselves by refusing to wear half-masks etc... I am not going to support them. Of course, once Covid-19 etc... is over or if its all revealed to be a load of trash then that's another story.
I'm not advocating a point blank refusal to wear masks. Because there's always the possibility, albeit remote, that Covid-19 is a genuine pandemic and that the actions taken by governments across the world are sensible and appropriate.
But since the virus is of little or no threat to most people and at the same time presents an ideal opportunity to roll out the mass digital surveillance systems that the conspiracy theorists have been warning about for decades, I think it's eminently sensible, and not at all paranoid, to consider all possibilities.
There are pros and cons to wearing masks from a health point of view, but the push to encourage/force everyone to wear them is a huge red flag, IMO. The propaganda is relentless. They're becoming fashion items. And worst of all, those who question mask wearing and protest against it are being labelled as selfish and disobedient.
If you see little problem with masks, what about contact tracking apps, immunity passports, vaccination identity cards? What would be your red flag?
