Basically some people like it and that's fine. You don't and that's also fine. But barging in with your dick flapping about shouting; "STOP LIKING WHAT I DON'T LIKE" just doesn't make sense.
You ask why do people like them, but then you immediately say how stupid you think they are. Do you genuinely care why some people like them or not...? But anyway... I can't speak for everyone, but I like how you have a calming, gentle wall with some hidden text in there. Cute little puppy saying cunt. Some of the text isn't nearly as subtle as it could be, sure, but really I think that's it; the whole contradiction going on. Peaceful background with the opposite in text thrown in.
