Wearing the masks for low risk, healthy people is not recommended by the CDC or even the WHO in noncrowded, low risk settings. The benefit of flattening the curve has been reached, and any further isolation not only has no benefit, but it works to slow the overall population acquisition of

Liberals often talk about forced vaccinations on the children of anti vaxers for the overall good of the rest of the population. Will they accept the same treatment? Of course not. Liberals don't want to have their own rules applied to themselves - just others.
In fact, these flat earth liberals are no more scientific than the anti vaxers.
