Can you be a Christian and heterosexual male and support gay rights? Can you safely enjoy Brokeback Mountain? Can you dress up like Kelly Clarkson for Halloween? According Michael Day of the University of Florida's Independent Alligator, yes, you can!
Evil is that which is harmful to our happiness and the good of society. How, then, can homosexuality be evil?
By my observation, it clearly makes gays happy. Any unhappiness it brings is probably from societal pressures and persecution. That's our evil, not theirs.
And homosexuality does society no real harm. If anything, gay marriage would indoctrinate the principles of a healthy relationship into the lives of millions more people.
