Morrissey ignores the basic observation that, by nature:
1) Lesbian women are inclined toward sports, while
2) Gay men are inclined away from sports.
This creates a big selection bias in the tennis player (and all pro sports) sample.
There does tend to be more lesbians drawn to sport, the same way an above average number of gay guys are drawn to professions like hairdressing. They are still a minority, but the percentage is higher than most other places. But still, you can't always go on stereotypes. I know a lot of lesbians, most of whom are very feminine.
We can't say for sure who is or isn't gay. That's what is bugging me on this thread. You don't know for sure that there is definitely a gay guy in the top 100. Of course statistically speaking it seems unlikely that there is none, but I'm sick of people trying to out someone with no evidence other than there own gaydar, which must be right
I don't think it's easier for lesbians to come out anyway. There are hardly any out lesbians on the wta tour, and players like Flavia Pennetta has acknowledged there is a lot of them. It's sad that in this day and age people still have to hide their sexuality. There has been rumours about Sharapova's sexuality, but that doesn't mean much. Most rumours are made up. But if they were true, there is no way someone with that many male fans and endorsements could come out.
Plus, on the atp tour there is a lot of homophobia. Tipsarevic is definitely not the only bigoted guy on the tour. Sport can be a pretty bigoted place unfortunately.
