The Oatmeal is a web comic that, a couple of years ago, did a piece called "How To Suck at Your Religion." It bugs me. It may seem late to be bringing it up now, but it still pops up in my Facebook feed and other places and -- according to his website -- is one of The Oatmeal's most popular comics, so I need to handle it.
Just so you know, I'm mostly indifferent about The Oatmeal in general. I'm annoyed more by its fans than it itself, since they gush about it a bit more than it deserves. I admit that it deserves something, since it's mostly okay and sometimes even funny or clever. However, even the harmless comics he does -- like ones about grammar (correct use of the word literally or how to use a semicolon) -- seem to only make those laugh who already know these things. I doubt that it actually educates those who don't.
This "How To Suck at Your Religion" comic is similar. It seems to be written to make atheists (or perhaps liberal believers) laugh and share it on their social media walls. It's (probably) not going to teach anyone to not suck at their religion.
There have been a handful of Christian rebuttals written about this comic. These rebuttals contain a mix of valid points (some of which are probably mirrored by me) and they also have stupid points that rise as a result of their religious beliefs (sorry, guys). So one reason I'm writing this is because I haven't seen too many rebuttals from atheists.
Also, mine is incredibly long, and things that take a long time to read is what internet users crave the most.
