There’s a difference between a controversial opinion and one of the strongest taboos in American culture.
While the unrestricted age of consent is between 16 and 18 in all U.S. states, the laws have widely varied across the country in the past. In 1880, the ages of consent were set at 10 or 12 in most states, with the exception of Delaware where it was 7.[104] The ages of consent were raised across the U.S. during the late 19th century and the early 20th century.[105][106] By 1920, 26 states had an age of consent at 16, 21 states had an age of consent at 18, and one state (Georgia) had an age of consent at 14.[104] Small adjustments to these laws occurred after 1920.
Damn Deleware, 7?!
It is one of those slight odd statistics, especially if it is similar in places where the age of consent is 18. It does however explain why there are so many different age of consent, and why it is hard for law makers to fix it to a number that make people happy.

Not to mention like every big rocker had a teenage girlfriend in the 1970s.
According to US HHS "over the course of their lifetime, 28% of young people in the US, aged 14 to 17, had been sexually victimized."
Compare that to 4.8% for the UK, also a country with a severe child SA problem.
The US is thusly quite anomalous, and is only really comparable to undeveloped nations in terms of CSA rates.
So when an American goes out of his way to defend forms of CSA on his personal webpage, unprompted, it can certainly be seen as symptomatic of this larger US cultural issue.
