Legitimacy when it comes to leeching?

But if you think about it. If someone owns a bishop which he worked hard for, then leeched up a character with his own bishop. Is that supposed to be baD?

Thats really just a branch of the general question, there will be differing opinions on this as well. While you worked to train the bishop, you didnt work to train the other character as the way it was intended in the eyes of some, but it goes the other way too, some people are fine with that since you did the initial work and it was your bishop, it goes both ways, the community is so seperated (and hypocritical in a lot of cases) on the issue of leeching that whatever you do someone will dislike you and someone will be okay with you, it all boils down to if you yourself find it morally acceptable, in my opinion.
