Actually, my mom was murdered gruesomely. I have better things to do than getting offended too much over people's word choices when I know that they're just venting and not actually trying to insult me personally.
That said, there's plenty of awkwardness when people assume that a person your age should have living parents and you always end up having to explain what happened when you get to know new people.
I come from a country with perhaps the most open mind on free speech, so there probably isn't going to be anything that gets under my skin - I probably use profanity too much as a result.
I only see "rape" on the internet and don't know how prevalent it is in real-life vernacular in English-speaking countries, but it's something I'm glad I don't see that much (outside of StarCraft 2 discussions).
I don't really know that many contexts a vernacular "murder" is used in, so I don't know about that.
Regardless, the victim isn't going to be able to take any offence.
