Heterophobia on LOGO TV

Ever watch a gay stand-up comic?
I watched a very butch lesbian the other night on Logo (the gay cable network).
Not that I found her particularly humorous.
Everything is gay this, gay that, gay, gay, gay.
Oy gevalt! We get it, you're gay!
Do you spend every nanoscond of your life doing gay things?
Now it bothers me not one iota when a gay comic wants to pander to his/her gay audience but why, oh why do they have to make "jokes" deriding heterosexuals?
Furthermore, why do heterophobic jokes cause screams of laughter in the audience?
Where is the "sensitivity" thay they demand for themselves?
What's good for the goose...
