It may be the case that people willing to participate in a mass gathering are not concerned about the virus, but the majority of ordinary Americans are not for sustaining the full force of lockdown measures.
Also the incentives are a total mess, when it comes to selecting people to interview at a protest; especially when most news outlets seem, at the moment, to have an editorial interest in justifying the lockdowns in their full extent (meanwhile journalists, unlike most Americans, are not themselves subject to the lockdown orders anyway).
P.S. there's a distinction between the subset of people who don't think the “non essential” economy should be locked down indefinitely, and the subset of people who will go out without masks to attend a mass gathering in protest. The latter is necessarily a fringe minority.
