I think you are great example of life in the conservative propaganda bubble. So misinformed.
Some things to explore and google.
1.) What does masking up mean? Who is the we in that statement? Can you post a reference to any reputable person who would say a kn95 or n95 or kf94 mask is not effective. Also what is the difference between an N95 mask and a cloth mask.
2.) How do vaccines work? What is a vaccine strain? Why is the Covid vaccine we've all taken less effective against Omicron? A good reference would be to google the flu vaccine and see how that vaccine is chosen.
Here is a good chart that helps with the differences in wearing different masks/no mask. Also this was made before the more transmissible omicron variant.
