re: Why are so many fans okay with these restrictions and think its logical?

It doesnt make you anti Vax to be wary of a shot that is not a vaccine in the general understood sense and has not been widely tested or distributed for years to see short term and long term side effects.

I'm also still waiting on someone to refute my argument based on the example of thousands of people packing baseball stadiums for months and no vaccine or negative test being required from what I recall. I'm sure that will change.
