Nay.
Are we really doing this again? Kissing is G-rated. If it can be shown to 3-year-olds then it is suitable content for the 13+ userbase of Imgflip. Kissing is certainly more suitable content for young people than “God hates f*gs” type memes and over-the-top mudslinging and a lot of other crap I’ve seen posted here, much of it by yourself.
Is it “unrelated”? Not necessarily. Any kind of image could be relevant with creative captioning and Congressional proposals like yours ironically strengthen the argument that it is, in fact, relevant, period. Otherwise, why vote on it?
It can’t be enforced anyway. Scar won’t allow it because it restricts free speech too much. And if you try to anyway, you’ll lose your mod again. We’ve been down this road before, man! Need I remind you the definition of insanity — doing the same thing over and over again and expecting different results?
