Why do many consider it wrong to find 15-19 year old women the most attractive?

I'm a 19 y/o guy who is going on 20 soon but I find younger women to be the most attractive physically. Specifically, only girls who are about 15 to 16 (depends on how they look. Sometimes a 15 year old looks much older than she is and a 16 year old looks her age). Now, it's obviously illegal to have sex with a girl younger than 16 in my state so I wouldn't do it. I probably wouldn't even date a girl younger than 18 because of maturity issues, however, I still find later teen girls to be the most attractive.

Lots of people give me shit about the 15/16 part, saying it's "too young" (I agree that they aren't mature enough, but we're talking about physical attraction) and that somehow I'm creepy for liking that.
(1.) You are biologically an adult about 16 years old, fully sexually mature. I'm attracted to their looks. If an 18 year old woman looked like a middle schooler I wouldn't find her attractive. So we're talking about how they look. However, most girls by 15-16 do look their age and look like women.
(2.) Plenty of girls these age like older men, sometimes MUCH older, because biologically this is how we're programmed. A lot of men also like younger women, but are afraid to say so because women tend to call any guy that likes older women a "pedo", even though pedos are attracted to prepubescent children, not sexually mature adults, like 15/16+ women are.

Like I said, I follow the law and I probably wouldn't even date a girl at the bottom age range, most like 18+ since younger girls tend to be too immature. I'm not going back to my high school every now and then "hunting" for a sophomore girl. I just want to know why people (mostly women) would consider just the attraction wrong.
