Can a Christian not be homophobic?

"The Bible clearly teaches that homosexuality is an abomination in the eyes of God! You must choose between serving God and indulging your sinful tendencies!" This book is for those who are willing to say similar words to people with a homosexual orientation. It is also intended for those who are told similar things. The book will also be useful to activists, believers and non-believers, who advocate for equal rights for queer people.
They will find here a reasoned defense against theological attacks. I am convinced that equal rights for queers in Christian churches is not just a demand of the "outside corrupted world" (as homonegativists say). It is also a demand for a healthy approach to Biblical theology.
