That's GP's point. 6 months ago it made sense for everyone to wear masks. Today it doesn't. If someone today insists that everyone should still wear masks everywhere, then they're doing so for political reasons rather than scientific ones.
It's ridiculous to try to turn that into a claim of hypocrisy and that everything is just politics.
Essentially 6 months ago you somewhat had the moral high ground because science was on your side, but now it's just personal preference.
If you feel safer with a mask, that's fine (it might do some miniscule good). If you wear a mask to show everyone where you fall on the political spectrum, than just own up to the fact that you're being divisive.
In terms of merely making a statement, then the anti-mask option would be something like wearing a shirt or mask with a message about how this whole mask thing is stupid.
The objection to people going maskless 6 months ago is not that they were making a statement, it's that they were endangering people in aggregate.
When you say "Was it lip-service and posturing 6 months ago or is it now? Do you value science or not?", that would only be justified if the science was specifically saying not to wear a mask right now. But that isn't true and has never been true. Wearing an unnecessary mask has always been fine.
Who's doing that?
Remember that, while the CDC is advised and informed by scientists, they are ultimately a public policy agency. The science matters, to be sure, but what matters most is that the best outcome is achieved, based on people's behavior.
I think they're recommending dropping mask requirements now not because it's the best science, but because vaccine demand has been dropping, and they believe that giving people real-world, day-to-day incentives to vaccinate will convince some of the people hesitant to get vaccinated. And I agree with them on that, and I think it's the right move, even if it carries some risk.
