This is something I am curious about as well. Because its commercialized messaging I've only noticed after all of these maddening events in our country the past few years. The public health communication, I feel, is genuine and not something I am trying to criticize. It is important to try to get through to those who are resistant to considering others by wearing a mask/practicing social distancing/getting vaccinated and appeal to their moral character. The t-shirts though, I'm stunned.
