It's a simple mater. Sexual orientation does have nothing to do on a job context.
There's no point on discriminate someone by its sexual orientation (also who the fuck is being asked for that on a job interview? I didn't see that on my entire life) and also there's no point on setting "quotas" like "hey company, you'll need to hire at least a 10% gay people", I've been saw things like this and it's just disappointing and seems quite unreal to add preferences based on sexual orientation on a context where this is not meant to be something relevant. Also this measures cause straight people to be discriminated.
If you got to chose between 2 people, one being straight that worked harder and one being gay and worked poorly you'll need to be able to chose the straight as you'll be silly for not hiring the gay on a reverse situation.

The issue here is government and law applied to inner life of people instead keeping the limits of them, we (everyone) are loosing rights day by day and we are fighting between us for stupid things like sexual orientation, being man or women or the color of our skin. Then there's people over us earning millions by laughing at the rest and this people doesn't care about any of those concerns that they put into the society.

People need to be pragmatic. Your sexual orientation? I don't care. Your religion? I don't care. Your color skin? I don't care. As long as it concerns to me, your acts are what makes you being you, nothing else.
