In France the age of consent is 15. Americans are such religious zealots.
"That the age of consent is 16 or less in most of Europe but 18 in some US states gives rise to some dissonance when discussions arise about the attractiveness and availability of 16- and 17-year-olds. 16 is actually common in the US (30 states out of 50), but not many seem to realize this- probably because it's 18 in California, where a lot of the US entertainment industry is based."
Tech industry is also based in California. This is a California morality issue not an American morality issue, there's no US wide agreement on what is an acceptable age of consent.
Maybe the other Americans are right on this one?
