Because we choose not to breed, not to give another pointless mouth to feed, another person to steal resources and cause global warming.
In fact, us gays are saving the planet, by spending all our money on interior decorating and eating out at Thai restaurants. As opposed to say spending all our money raising some idiot child that will probably end up just sitting unemployed stealing from the state because all the other working class breeders childrens took all the jobs in Macdonalds and uninterested Nigerians keep taking all the cleaning jobs.
Therefore, sir, we have a right to rub it in your faces as you are destroying the world with your penis's while us fabulous people bring you joy and fashion and wonderful new fittings for your home.
So fuck off, straighty.
Also Gay adoption is a myth, like unicorns, so dont counter my argument with that. Yes.
