You could be right. I have a hard time seeing it, though, since other studies support Dr. Cameron, one of which is the CDC (per the article). Plus, the study is published in the refereed scientific journal Psychological Reports.
I have a hard time seeing it too, because there's every reason it seems to me that even if generational differences in 'coming out' were skewing the life expectancies lower in this study, the gay men should
still be dying earlier than the lesbians, just because of AIDS.
Strange..
