My guess is a moderator did not approve this because it's merely stating a subjective opinion and hoping to get upvotes because people agree with it. As far as we're concerned, we don't care what opinions you hold (as long as they're legal etc.), but we're actively trying to feature images that are creative/interesting/funny/new/etc, as described in the submission guidelines. This opinion has been stated billions of times on each side of the argument, and each side will continue to just say "no you're wrong" to the other side, and it's just not the type of thing we want on Imgflip. There are plenty of places you can find on the internet to have a raging debate about politics or religion, and some of that will certainly happen on Imgflip, but we're not actively trying to make it happen.
