Instead of "hate" the sin, I believe we are called to be concerned. In reading the final chapters of Genesis, the themes focus on lack of discipline, primarily sexual discipline. Nations without discipline fail. Maybe there are no homophobes. Maybe what some have is more like ancestral memories of when homosexuality, etc. become noticeable and publicly shrugged aside, we, a a whole, were living in a society noticeably in decline. This decline did not begin with homosexuals. It began with the lack of discipline in majority (heterosexual) relationships where divorce and sex outside of marriage were shrugged aside long before homosexuality (minority relationships) became an issue.
If the majority are not going to practice sexual discipline, why should the minorities? Does "loving" the sinner mean we should be accepting of all behavior? How many of us accept divorce? How many of us accept sex outside of marriage all in the name of loving the sinner and hating the sin? Until the majority looks at their own behavior and seriously, even sternly, reject our own lack of self discipline, sexual discipline, we have no business sanctimoniously asserting we love homosexuals and hate their sin. If we, the majority fall, guess who falls right along with us. And that is not loving our fellowman.
My guess is we are going to continue to accept divorce and sex outside of marriage, therefore we can be safely ignored by the minorities who are only practicing the freedoms (lack of discipline) the rest of us follow. We have no authority to cluck over minorities. None.
