What is so immoral with homosexuality among two same-sex people that are attracted to each other? How does that deprive someone of deserved freedom? How does that enslave the whole human race or vast segments of it? How does homosexuality create poverty? How does it stifle science? Are gay people parasites on society? Do they waste innocent people's time? Perhaps the "gay pride" parades do more to misrepresent true homosexuality and, as such are objectionable--but it is none of anyone else's business when two men or two women (or even groups) have sex with each other.
On the other hand, the Abrahamic religions do enslave whole populations. They have created oppressive rules, suppressed women, and murdered those who do not believe. They have all stifled science, started pointless wars, steal money in the name of salvation, and work toward communism. Do we hear too much from the washtowel against those practices? And, when we do hear about it, is it only about those "other religions" while they themselves do the same thing and are exempt?
