Joseph Stack, the enraged man who flew his plane into the IRS building in Austin, was initially seen by several liberal-left pundits as prototypically right wing; the most common suspicion was that he was a tea party activist. But then it was shown that he was also anti-Catholic, and that confused the left to no end. In his suicide note, Stack railed against the “wonderful ‘exemptions’ that make institutions like the vulgar, corrupt Catholic Church so incredibly wealthy.”
As a matter of fact, the anti-Catholic camp is quite ecumenical—members can be found on the right, as well as on the left. But it is revealing that the left lays claim to Catholic bashing.
