I'm not very familiar with US, but over here „conspirational crowd“, based on thinking patterns, is very diverse. But media seems to flag as „conspirational“ only a portion of it that comes to vaccines. And a lot of people who had issues with vaccines also have issues with corruption and other, let's say, tricky topics. Yet if we want to stop „conspirational“ crowd and make people fall in line with some topics, I'd be worried that it'd affect people concerned with other topics too.
