I think it depends on what was the context. I think some people are more sensitive to "political correctness" while others don't think much about it but they don't mean anything negative. Was your T trying to really offend those people, could you feel hatered, judgement... or was her message neutral and her only "crime" was not using the latest invention of PC culture language?

I certainly think many people are racists and bigots, but also the demands for using "proper" language are gettiing increasingly ridiculous. Basicaly anything that a person says nowadays can be interpreted as offensive. Even when I say I like breathing people with asthma could get offended.

So well... my point would be the whole context and the actual message she was trying to say, not individual words, especially if it's something that's commonly used.

If her message was indeed negative, if she was really judgemental and or vulgar, then I would stop seeing her.
