The issue is a penitent sodomite becoming a public teacher, a de-facto DOCTOR OF THE CHURCH. Teaching the Church faithful, the Church militant, being a spokesperson, having a louder/larger voice than the average layperson.
THAT is the problem.
Forgive them? sure. Give them the benefit of the doubt? Sure. Be charitable? Of course. But you don't put them in a high teaching position of power, nor do you have them run your Boy Scout troupe! It's simply NOT PRUDENT.
Not everyone has a right to be a teacher. Not everyone has a right to run a boy scout troupe. Not everyone has a right to be in charge of finances. But if you're a repentant sodomite, thief, etc. you need to accept, AS PART OF YOUR PENANCE, that you no longer can expect to be trusted with those roles. And that shouldn't bother you. IF you are truly penitent.
