Well. Piracy is "theft" of possible income of IP which different people feel differently. Since money makes the person's world go round, anything that prevents you earning your money legally can be a problem.I don't think that piracy and gay marriage are in the same moral basket. Because one is innocuous and the other is unethical.
I wouldn't consider gay marriage unethical. It might be consider unethical in religious sense, but not everyone have the same religion/belief. I believe that everyone should have equal rights as a couple if you are going to give rights to couples.
