This paragraph is rather off topic, but it's something I've been thinking seriously about lately. Think about it this way: if you come out and say that black people suck, people will generally be upset with you. Black people have had a long and hard fight to get this far, and while there's still a lot of discrimination against them, at least it's not cool anymore. On the other hand, if you say that you hate Muslim people, it is likely that people will support you and won't say anything. Because right now, being racist against the Muslim people is rather acceptable. If you frequently refer to women as "bitches" and hang out at strip clubs, the vast majority of people find that perfectly acceptable. The point of this paragraph is: most of us see and hear about racism and sexism on a daily basis, and even practice is, but it tends to be overlooked. This "tolerant" society we say we're in isn't as great as it's cracked up to be.
Here's
a good story about sexism in the modern world, and how it can be extremely harmful to women. It's a long story, but to summarize it: a forum for law students started talking about certain girls, which eventually led to harassment (online and at school) of her and many others, in a way that will likely affect her career and the rest of her life. It's a really good read, and looking at it from the guys' perspective, I can see behaviour like that all the time.
My point is, yes, it's a harmless joke. But making jokes is a way of becoming comfortable with something that you ought to know is wrong. Prejudice often leads to discrimination, which is something that is rampant.
I honestly can't believe you're comparing a joke that has undertones based in sexist prejudice to murder which is the unconsented deprivation of life.
Perhaps you missed the part where I said that they're both destructive, but murder is "less severe, obviously"? You're missing the point of that statement, which is that some things shouldn't be tolerated (in response to Crazed saying (or implying) that everything should be tolerated). I'm not saying that they're the same thing, which is how you seem to have taken the statement -- rather, I was using murder as an example of something that shouldn't be tolerated, nothing more.
