The last 2 pages of this thread are the perfect illustration of why a word may cause impact/harm that the speaker might not intend.
In other words, be careful what you say. If you feel that you should not have to police what you say, because you may offend those around you, please, step from behind your computer, visit the near East Side of Cleveland, and scream racial slurs to your heart's content. Context matters, doesn't it?
Video games have, through the constant use of words many of us know better than to casually toss around, caused some people to just use these words without thinking... or they do think, and, due to the anonymity of the internet, dont care/think its funny/do it for lulz/whatever.
It isnt funny. It isnt cute.
I think the moral of the thread is "even though its the internet, what you say has an impact. Have a teensy care about what you say and how you say it, please"
