You make some good points and I will go a bit further: I have no argument with anyone being gay. It's none of my business. At the same time, I believe that the research will back up my belief that children need both a mother and a father. So, responsible gay people need to accept that there are things they simply can't offer. Anyone who truly cares about children will choose what's right for the child. As we all have to do when we're grown up, they need to accept that there will be limitations on gratification of their desires. Novel concept in this day and age, eh?
It is when you are being taxed to care for the medical tragedies that result from such behavior.
