Because none of this makes sense. Any virologist (without vested interests) will tell you a virus is very very small (0.1 micron) and able to get through and around any mask to spread at any Woolworths or Coles or Bunnings and so on. A mask indoors at a hospital or nursing home does cut the risk somewhat and is a good idea. Do not spit all over somebody you are talking to anywhere is a good idea.
Screens make no difference and social distancing makes virtually no difference either as aerosols carry a virus not just spittle. The definition of "pandemic" was changed and the flu magically disappeared. PCR tests do not identify a live virus and cannot differentiate between many strains of common cold or normal seasonal flu (which can kill very sick and very old people too - and still does). Oh but protests for BLM are no problem yet protests for our human rights are dangerous. I am so sick of this whole subject. Be informed or get the jab I really am losing the care factor.
