Every business has the right to hire people who uphold what they believe the moral character of their institution is. In fact, I would say it’s scandalous for a person to employ someone whose very presence might convince other people to sin and be a threat against the public good. Consider for example a pedophile, who had never touched a child, but think his urges are fine and healthy, and tells his customers when they ask that he’s not a pedophile for “health reasons.” This would certainly be scandalous, and a Catholic employer, just like he has the right to not give people birth control to protect the common good has the right to not feed the public, children, or other workers false teachings on sexuality through the behavior or beliefs of one of his workers.
Also, goofyjim, it is contrary to church teaching to say that homosexual urges are anything BUT disordered. If you believe these urges are prenatal, and don’t pertain to ones childhood environment, despite the fact that logic and psychological research (and I don’t mean the APA) clearly argues against this, or that SSA doesn’t constitute a psychological disorder, when men and women with SSA are consistently over represented in other disorders (30% of serial killers have same sex attractions, compared to the normal 3-5 % of the overall population), this in no way makes the attraction any less disordered, since it is an attraction to sin.
2358 The number of men and women who have deep-seated homosexual tendencies is not negligible. This inclination, which is objectively disordered, constitutes for most of them a trial. They 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.
As another posted showed above, there is such a thing as just discrimination based on beliefs or behavior. Depriving a homosexual of the right to life would be a grave injustice. Restricting his presence in society, by depriving him of a house situated in a healthy Christian neighborhood or a job in a company of a moral character, regardless of what it does, would not.
