There's truth to that. Tell people that they have 5+ options to improve their safety and none of it is required, they are much more inclined to consider all the options. Ivermectin, HCQ+Azithromycin+Zinc, vaccines, Vitamin D and some sunlight, etc. Tell people they have only 1 option (vaccines) or else, that's an ultimatum. That's much more likely to be met with derision, skepticism, and anger.
