I've been sick once in the last 2 years and that aspect of masking has been fantastic. I will continue to mask up until I'm legally told that I can't (which in the southern US is actually a law in some places due to the unfortunate existence of the klan...)I'm gonna be masking for a long time since I don't know who is carrying it. Plus I haven't been sick at all.
Also there are folks who are physically unable to receive the vaccine and other folks who are immunocompromised that will likely die if they become infected, regardless of the variant. All these attempts to return to "normalcy" seem like a big eff you to them, if you ask me.
