If there weren't hate-filled hobophobes threatening and bashing
GLBTs there would've been no need for this, and no questions of
'what if it's the other way around'. 
They don't need to keep lesbians out though, do they?

An Australian hotel catering for
homosexuals has won the right to ban heterosexuals from its bars so
as to provide a safe and comfortable venue for gay men.
In what is believed to be a first for Australia, the Victorian
state civil and administrative tribunal ruled last week that the
Peel Hotel in the southern city of Melbourne could exclude patrons
based on their sexuality.
Australia's equal opportunity laws prevent people being
discriminated against based on race, religion or sexuality.
The hotel's rules warn guests that it is geared towards gay
men.
But Peel Hotel owner Tom McFeely said the ruling was necessary to
provide gay men with a non-threatening atmosphere to freely express
their sexuality.
"If I can limit the number of heterosexuals entering the Peel, then
that helps me keep the safe balance," he told Australian radio on
Monday.
McFeely said that, while the hotel welcomed everyone, its gay
clientele had expressed discomfort over the number of heterosexuals
and lesbians coming to the venue in the past year.
He said there were more than 2,000 venues in Melbourne that catered
to heterosexuals, but his hotel was the only one marketing itself
predominantly to gay men.
Victoria's state human rights commission backed the ruling, saying
it was in line with equal opportunity guidelines defending the
rights of groups subject to discrimination.
Commission chief Helen Szoke said the hotel's gay clientele had
experienced harassment and violence. "(They) also have felt as
though they've been like a zoo exhibit with big groups of women on
hens' parties coming to the club," Szoke told reporters.
McFeely told the radio that the hotel had received homophobic
telephone calls since news of the ruling was made
public.
