The message of Christianity is love, not hatred. You don't convert people by making fun of them and their religion, but by loving them. You don't serve by making yourself famous. You don't go against the church and give up the pastoral ministry of the priesthood in order to keep dealing with people in hatred. May God show him the error of his ways.
What hatred are you talking about? Can you give examples?
Much of Islam, well, falls under ridicule only because it cannot withstand scrutiny. There are no two ways about it. Take for instance the account of Allah revealing Quran so that Muhammad's daughter in law could divorce her husband, Muhammad's adopted son, so she could marry Muhammad. AS if that wasn't enough, the Quran bannig adoption so as to uphold Muhammad's moral purity: I have seen many Muslims denigrate adoption because the Quran says you can't be made someone's son if you weren't born it, that adoption is "unnatural" nay "perverse." Then the "Story of the Honey" (a tale about the wives of Muhammad fighting about their turns sleeping with him, and with one in another's bed). And I haven't even brought up the issue of pedaphilia with Aishah....
Then there's the law that to be reconcilied to a divorced wife, you must have her have sexual intercourse with another man first.
Now, the PC crowd might excuse it by saying "different times, blah, blah, blah" But Islam says this is "the Best of Mankind" the Quran putting him up as the "Good Example" (33:21). Try to make a family morality based on the above: Islamic law/shari'ah does (that same law that the Islamicist who killed the military recruiter in AR says made him do it). So it is behavior not to be excused, but emulated
I'm aware of the other issues you bring up, but since you bring them up, I'd rather you explain them.
