Why dont girls understand why dudes dont like tattoos(and piercings)?

I've read a couple posts recently about guys who dont like girls with tattoos, and generally the guy comes off sounding like a judgemental jerk and the people who support girls with tattoos and piercings win the arguement. In most of those posts, the guys say something like "girls with tattoos are dirty and trashy", which is often times true but by all means its not a given. That instantly makes the argument against girls with tattoos seem like a terribly one sided and stupid argument (like gay marriage or abortion), when in reality the issue with girls with body modification is extremely simple. The reason most guys dont like girls with piercings or tattoos is.......Because their not ATTRACTIVE! Girls bodies are adored because of their curves, their smooth and unscarred skin, and ultimately just natural beauty. I think i speak for most men when i say that piercings or tattoos ruin the beauty, and the prettyness (i know its not a word) of the female body. I personally wouldnt want to be in a relationship with any girl with a tattoo or piercing (not ear of course), not because i think they have a billion STD's, but because they look UNNATURAL. I dont care what the tattoo is, it looks unnatural! I dont understand why girls never seem to realize this.
