Try to follow your logic:
1. You said this (and I’m assume by this you mean his contracting Covid) would have been completely avoidable had he followed everything he railed against.
2. He railed against mandatory masks and social distancing. I think. I don’t follow him that closely.
3. So had he had worn a mask and practiced social distancing he would NOT have caught Covid because.....
4. Masks and social distancing is guaranteed 100% to protect someone from Covid based on your comment quoted in #1 above (completely
avoidable).
