It’s actually probably fairly accurate. there are about 2.8 million serving the armed forces; active and reserves. 65k would be 2.3%.
So is his model based on the assumption that is roughly the same as the population at large? Half the popluation at large? I’m wondering how he got the figure. It seems high given military culture versus the “culture” of the gays and lesbians I know (although I do know one lesbian who entered the military).
