When did it become controversial to say that my Rabbonim are correct and other Rabbonim are not?
That’s not what you’re saying. You are saying they are not only incorrect, they are incompetent fools who are taking a position with absolutely no logic or reasoning behind it, and are pro death.
Were you not disappointed two years ago when several Rabbonim were fooled by fake news and started saying that vaccines are dangerous?
Confused, not “disappointed”. I’m not that arrogant. And that’s a small minority. In this case it’s not. So you are the one who needs to rethink your position. Not to change what you do, or even your opinion, but to realize that there is another side here, one which doesn’t see mandated mask wearing as merely uncomfortable.
I can’t find any flaws with that logic
Except that throughout the generations, rabbonim and poskim have always trusted information from people they deemed reliable, and many gedolim, not just R Elyashiv, paskened past 80.
You are for some odd reason assuming that all of the rabbonim who don’t mandate or wear masks haven’t read CDC guidelines. That’s wrong. There’s no lack of knowledge of the metzius here, as I have explained.
No Rav or Rebbetzin would say that the halachos could be ignored if it’s too hot out. So the same with masks. Uncomfortable, but important.
It’s starting you right in the face and you missed it! These rabbonim are paskening that there is no chiyuv to wear a mask! They include some of the biggest poskim (certainly in Eretz Yisroel). No, they are not missing information or being fed misinformation. They just don’t agree with you.
