Well! They want money from everywhere else, constantly holding out their hands for that which they didn't lift a finger to earn. Consider the fat tax, sugar taxes, tobacco taxes, the global warming sin tax(cap and trade) and on and on. All kinds of taxes that are based solely on trying to "help" you make better decisions by dissuading you economically from certain other choices. I don't think anybody could ever argue that what one man does to another man's body is healthy. Therefore, if it's unhealthy, will it be taxed? Will there be a gay tax?
