Uhh... There's actual real world data showing condoms are 87% effective with actual normal use (not perfect use). Where's real world data showing masks are just 5+% effective? I'm not looking for excuses to dismiss papers, I'm looking for papers that actually prove something in the real world.
So you claim, but your very next sentences contradict that entirely.
"I don't care if some study finds a mask reduces droplets by say 80%, does that translate to any results in the real world?"
Translation: You don't care about the mechanics and will simply assume that the results are invalid in a "real-world" context. While you're at it, would you like to also argue that car safety tests mean nothing because they use crash test dummies?
Dismissing lab studies for not being "real-world" fundamentally misunderstands the entire purpose of controlled experiments in science. The point of a controlled setting is to isolate the mechanic; in this case, the physical effectiveness of masks at blocking droplets and aerosols. That's not a bug, it's the entire method. We do the same in crash safety, drug development, and industrial design.
Real-world effectiveness depends on a ton of factors - usage, compliance, environment - but lab studies establish the baseline: what the intervention is
capable of doing under correct usage. If you ignore that, you're not arguing against masks, you're arguing against the entire scientific method.
It’s one thing to say "real-world mask effectiveness varies," which is true. It's another to pretend lab-demonstrated efficacy is irrelevant, which just isn’t a serious argument.

"Does the 20% still get you sick anyway?"
Translation: Nirvana Fallacy. The existence of imperfect protection - even when the overall rate of protection is very high - is used to claim functional lack of protection entirely.
--
"Does the 80% matter when you usually get sick from people you're around for prolonged periods so you getting the constant 20% vs 100% even matter?"
Translation: Openly looking for outliers and edge-cases to provide a pretext to dismiss it, irrespective of proper application and safe practices.

"Also, covid is airborne so protecting against respiratory droplets (yes, I know airborne is still technically droplets but smaller) doesn't mean much. Remember, it took them like a year to finally admit covid was airborne."
Translation: Continues to misunderstand the concept of airborne to argue that masks can't have any effect on the transmission of airborne viruses, despite that being the
exact scope of such masks. It's precisely because Covid is airborne that masks are useful in slowing its spread.
And let's get into that one a bit more, because your statement is so deeply confused. If a virus spreads through the air, that is
exactly when masks are most helpful. It’s the reason
respiratory PPE exists in medicine, industrial hygiene, and pandemic response. To say masks don’t help against airborne viruses is like saying umbrellas don’t help in the rain.

"Why couldn't they simply do cluster randomized controlled trials instead of all these rather pointless studies? It's like why try to figure out how many people actually got covid using bad data when you can just do a seroprevalence study."
Translation: It didn't provide the data you wanted so you dismiss them as "pointless" and "bad data" while you quibble that the studies should have used different methodologies that your very suggestion makes clear you do not understand.
Did Cochrane find any actual concrete evidence that masks FOR SURE indeed reduce infections? No, they did not. That's all I care about. It's on you guys to prove masks do anything and you haven't. You can't even say masks reduce infections by as low as 5%.
Repeat after me: It didn't find 'concrete evidence that masks for sure reduce infections' specifically because THAT WASN'T EVEN A QUESTION BEING ASKED BY THOSE STUDIES, which focused on the effectiveness of
messaging to mask up rather than the effectiveness of
actually masking up.
Even then, Cochrane made a neutral statement: that evidence quality was too low to draw firm conclusions. But you’re asserting the opposite. Not "we can’t tell," but "they don’t work." That’s
not what the evidence says. And again, Cochraine went out of its way to clarify as much.
At this point, you’ve made it abundantly clear that no study - not real-world, not mechanistic, not randomized - will ever meet your bar unless it already agrees with your view. You dismiss every kind of evidence as "bullshit," refuse to engage with what studies
actually say (even when the authors themselves correct the very misreading you're promoting), and rely on fallacies like "it’s not perfect, therefore it’s useless."
Cochraine's study does not say what you claim it did. The Bangladesh study
did show reduced infection. The physics of aerosol containment
are well understood. But you’ve made it clear
none of that matters to you, just whether or not it aligns with your pre-set narrative.
