Laws single out particular people based on preferences all the time, if you define "we won't subsidize/will penalize your choices" as "single out". Some people prefer to marry men, they can't get singled out. Some prefer to rent a home rather than buy, they do get singled out. Others prefer no health insurance, they also get singled out. Or as it relates to gay marriage, people who prefer to be single get singled out. The text pretty clearly says you can't pass a law "no voting if you have gay preferences". That's very different from requiring legal privileges for gay relationships.
