Again, you have lost me.
There is a difference between saying…
- Unjust killing of innocent human beings is wrong, and
- Joe acted unjustly because he murdered an innocent human being.
…just as there is a difference between:
- Engaging in homosexual activity is disordered, and
- Joe is engaging in homosexual activity.
In the case of 1) I don’t need to have any particular knowledge of anyone’s actual behaviour to conclude that the murder of innocent human persons is morally wrong. That is an entirely different issue from knowing about individuals who kill others under mitigating circumstances, mental issues or have extraordinary burdens to carry that may have made them act immorally.
Even in the case of 2) it is entirely appropriate to draw a moral conclusion about Joe’s act purely on the basis of the act itself.
Likewise, a conclusion about the moral status of homosexual behaviour can be made quite independently of whether any homosexuals exist or are personal acquaintances. One does not depend upon the other. The moral rightness of murder is not affected merely because a murderer happens to be a good friend of yours. That serves only to bias the moral judgement.
By your reasoning, someone who has, in the past, murdered another person would be committed to promoting murder and teaching his children that murder is permissible or at least refrain from speaking about the wrongness of murder because he has committed murder in the past and would be hypocritical making it out to be wrong when he has not righted the wrong he did in the past - obviously he cannot bring back the dead.
Your logic is utterly misconceived.
I could be a smoker (or sinner) who clearly knows smoking (or sinning) is bad and try to clearly express that correct understanding of reality. Doing so does not make the person a hypocrite unless there is intent to deceive or profit from the deception.
A crack addict who fully realizes the depth of his anguished situation is not a hypocrite for warning others about the dangers of crack use. A bigger hypocrite, in fact, might be someone who has never tried crack but convinces others to use it because he will profit enormously from their addiction to it, even though he himself is not even tempted to use it.
The way I see it is that we are all addicted to sin. Like a bunch of drug addicts if we merely talk each other into continued sin we do no service to anyone. To say, rather, “You know, what is happening here is wrong and does not benefit anyone,” is at least a beginning of the realization that addiction (sin) is a dead end. Of course, there will be those who continue to be enamoured by sin, and do not want to give it up, who will protest with, “Who are you to judge?” The question to ask, however, is if those protestors really have an interest in the welfare of others in mind when they promote the “keep sinning” and “don’t be bothered by those who judge” attitude.
