While "homosexual" acts are sinful and cannot be condoned, so are hatred and discrimination. The argument I make about same sex attractions being disordered must not be used to discriminate against people with these attractions. The only Christian response to persons with same sex attractions is love and compassion.
No person that claims to be a Christian can discriminate against anyone who has same sex attractions. This, however, does not mean that a Christian should allow legislation to pass that would allow what is call "same sex marriages." Stopping same sex couples from joining in what they call a "marriage" is not discrimination, but is the only responsible thing to do for these couples and for society.
