How you rationalize that hypocrisy so easily in your head is beyond me.
We ban accounts that post like this, because it's so destructive of the community we're trying to have here. If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and sticking to the rules, we'd be grateful.
Additionally, varying levels of contagiousness and mechanisms of spread absolutely make actions more effective for some diseases and less effective or not effective at all for others. This is not a controversial statement despite your dramatic insistence on ignorance.

If 90%* wear masks and the R-factor of the "flu" is is low enough it "disappears". But if the R-factor for covid is high enough it still spreads even if 90%* wear masks (10% don't).
It's mindboggling how simple simple thinking can evade people.
