Here's what I'd probably do. Hand him or her copies of the published studies and say, "this isn't me trying to tell you Leronlimab is worth considering for anyone who is severe or critical with Covid. These are emergency use results and explanation of the mechanism of action published in reputable journals from the former head of virology at Stanford and doctors on the front lines in places like Montefiore hospital in NYC, UCLA, etc. It's not pie in the sky, it's been tested long term in HIV and it's proven safe in both HIV and Covid emergency use patients, even the sickest patients, like transplant and ECMO patients. Please take a look for yourself."
