If I happen to think that it is funny, who has the right to say that my opinions or the feelings that the "sexist jokes" bring to my brain are wrong? Obviously one should also try to minimize the amount of content that may possibly cause harm to any number of people in the target audience, but the problem has a very abstract nature going all the way down to how and where to say what to whom and who gets to decide whats right and what's wrong.
I often laugh at sexist jokes concerning both men and women. I don't take those jokes personally but I also agree that one has the right to disagree and express their opinions towards the content of different media. (if-by-whiskey?..)
