1.6% by of the population the last study
I saw that study too. It needs to be repeated often.
I saw a Catholic Priest on late night tv a couple of months back who stated that 10% of the population was "gay" and therefore, it stands to reason that 10% of Priests are "gay" also. No one challenged his ridiculous assertions.
By the way, the moment I saw him, my queerdar started pinging.
