Because you absolutely, positively always refuse to answer questions or address issues that are inconvenient to your narrative. Because you never once can bring yourself to ever give a political opponent credit for doing something right. Because you never once can bring yourself to criticize an obviously absurd political stance a Democrat takes. Because you insist people look at your links while refusing to look at theirs (does Dr. Risch come to mind?).
The only provision where I'll even come close to agreeing masks have SOME effectiveness is if everyone is wearing an N95 mask properly 100% of the time. And that's never going to happen, because human behavior doesn't work that way.
If you don't want to acknowledge the obvious truth that cloth and surgical masking is next to useless in preventing viral infection, as 10 RCTs post World War II showed, that two major masking studies during Covid showed zero effectiveness (one in Denmark, one at Parris Island), and zero difference in case rates in North Dakota, South Carolina, Georgia and with my two kids' schools, fine. It doesn't change the facts of what exists if you put your fingers in your ears and hum loudly.
Finally, I get not wanting to admit you're wrong. Very few people do. I get not wanting to acknowledge possibly being wrong. But what I don't get is your refusal to even acknowledge...even acknowledge... contradictory data exist. Not on just masking but any subject discussed here. That's just plain weird, Ty.
