What they post about Catholicism says more about their own faith than it does Catholicism.
They post the same “gotcha” questions over and over and over and over. That is, they THINK their lame-o quips are “gotcha” questions.
Their favorite, of course, is their version of “Papal infallibility.” You know, the Catholic teaching that Catholics must give the assent of divine faith to every burp from the Pope.
