This is always the argument given. It is not a valid argument.
Kind of like a link to Mad Magazine, I think; anyone needing more than that as a clue that this is more about entertainment and satire than literal news should not click through; different styles of humor for different people.
They have a wonderful ‘bite’ if one really understands the Bible and Christian theology -and a bit of silly stuff (as a bass player, their story about the church bass player who found out that he’d been unplugged from his amp for the past four years crosses all denominational lines) at least several people find them funny. OTOH, there are styles of humor I just don’t care for, to each their own.
I will be sure to include a ‘Satire’ tag next time I post something from them.
