> But then again, the CDC was pushing the idea that getting vaccinated means you won’t get sick so I guess believing the CDC holds some scientific validity is an error to begin

There was a chance that this was going to be true. It didn't turn out that way. You're basically blaming them for trying, or what is your point?

> but study after study comes out showing they don’t stop spread

I'm curious to hear what studies you were thinking of. FWIW, N95 filter material has been repeatedly seen to block viral particles.

In the Cochrane review [1] they found

> relatively low adherence with the interventions during the studies hampers drawing firm conclusion

That is, studies which took a random group of people and said "please wear a mask, so we can see if you catch less $DISEASE," weren't effective...because people wouldn't wear the mask. This is, I think, a useful result--but it doesn't mean that wearing a mask doesn't stop disease from spreading; it means that telling people to wear a mask doesn't work so well.

> it was dubious as hell when they first pushed it

But why? Why was it dubious that respiratory protection would be effective against a respiratory virus?

> but study after study comes out showing they don’t stop spread

But does it stop individual infection? Studies show that lower quality masks and poor masking rigor may mean it's not effective for a large, lax, population, but do you have evidence that the proper use of an N95 doesn't markedly reduce the chance of an individual becoming infected with COVID?

I also would like to know what percentage of people masking at the event was infected. A lot of interesting data points are missing.

I don't recall the CDC saying that if you got vaccinated you'd never ever get sick.

COVID vaccines have a well measured non-zero efficacy.
