By "scary" are you referring to enplanements? These are revenue generating passengers (135 and 121).
I believe transparency is imperative and so would laud sites like this but the Pew folks need to add a column for economic impact. I'll grant that for an airport that is very difficult to quantify and generally the number is skewed by the agenda of the study author.
However, I still ascribe that in order to be European country you have to have a beer and a soccer team and in order to be a US town you have to have an off ramp, a railroad stop and an airport.
It is totally appropriate for the government to pay for a portion of this infrastructure from the general tax pool. Its just like the highway system.
