This whole thing is actually rather simple, if one holds true to the one true faith, which neither Martin nor Ruse do. The Catholic Catechism teaches: "[Homosexuals] must be accepted with respect, compassion, and sensitivity. Every sign of unjust discrimination in their regard should be avoided. These persons are called to fulfill God's will in their lives and, if they are Christians, to unite to the sacrifice of the Lord's Cross the difficulties they may encounter from their condition."  To the extent Ruse insulted gays and lesbians with the broad brush that he did, he violated the foregoing "commandment."  It was a sin.  Martin, for his part, exhorts us to reject Church teaching on homosexuality, and to regard homosexual CONDUCT (as distinct from the state of simply being homosexual) as perfectly acceptable, sinless.  To the extent Martin does this, he was wrong, see RC Catechism sec. 2357, and Ruse was right.  Ruse's provocative language, however, did the Church's cause no good.
