We do not criticize imaginary groups of people. This includes the imaginary group of people called “Gays.”
Now, people who call themselves “Gay” are actually Gaypracs (see http://uspsych.org/2012/05/25/gays-versus-gaypracs/). Gaypracs are sexual perverts and suffer from a mental illness (for example, homoneurosis or homopsychosis). They also exhibit a moral deficiency.
