As long as everything is made jokes about, it's fine. Just gunning for one thing with jokes, but not doing other one's because it's not appropriate, isn't fair. And isn't right.
That's why I like comidians like Frankie Boyle, he hates EVERYONE. Everything. He's not racist, he hates everything equally. Admittedly he does make some jokes a little too soon, sometimes you just shouldn't... but still...
