The breakdown appears to be: 16 years in 27 states; 17 years in 8 states; 18 years in 15 states. That leaves more than enough states (23) for the purpose at hand. The fact of the matter is that the movement is virtually nonexistent in the U.S. because nearly all states already have uniform age-of-consent statutes as a matter of course.
However, that said its still disconcerting that the rush to have ability to have sex with a minor generates so much energy.
There's little evidence that age-of-consent laws generate much energy, nor did I ever imply as much. In fact, they tend to be the very last vestige of discrimination that any general gay rights advocacy organization confronts. If you survey the websites of the groups I noted above, you will soon find that this issue is the most difficult to find much discussion about. Perhaps your blinded by your backwards approach, which as you pointed out is searching for age-of-consent and coming up with a disproportionate number of gay-related sites. I've already explained the reason for that.
Perhaps if you instead search for gay activist websites, and then come up with a percentage of those that deal with the issue, you will get a much better perception of just how much "energy" this does or does not generate for gays.....
Again, I could understand the case beign made that we ought to raise the other ages to meet the higher gay age but that isn't their quest.
I'm unaware of any objection in any case where this has taken place, nor am I aware of any objection by gay rights organizations in case where uniform age-of-consent has been increased, nor do I have any reason to believe they would object if that were the case.
The desire to lower their age to 16 in most states is in itself very telling about the nature of the importance of gay relationships with minors.
No, it's not.
One wonders why there are not enough partners at the age of majority.
You will have to consult your own fantasy world on this one, since the evidence does not support this as the reason for advocacy toward uniform age-of-consent statutes.
Even by your own admission gays are preoccupied with the age of consent given that nearly all states have uniform rules.
