That's you. Many people do, so it's better to not use the words, especially since there are alternatives.
For SC2 to grow to Broodwar levels of long term sustainability and mass appeal, it has to be able to attract a wider audience and lose the man-baby stigma. That won't happen if people are raging over losing and saying offensive words on stream for thousands of people to hear. People want to be able to watch this with their families, kids, girlfriends, etc. and that's not really possible if you've got people talking like Destiny.
Broodwar's audience was ~50% female because they managed to keep it professional and carefully manage it's image and market it's players. Being able to get both males and females means more advertising dollars, which means sustainability. The current SC2 scene is losing too much money to last much longer. Investors are only backing these tournaments because of the hope of it growing enough to become self sustaining and even one day profitable, but that can't happen if the audience is limited because of childish and easily corrected things like offensive words being said in public turning off viewers and advertisers. If HotS is out this Fall and by the end of the year professional SC2 isn't any closer to sustainability, I expect 2013 will suffer cut backs in prize pools and possibly salaries.
I would rather professional SC2 succeed than have it fail because Destiny and those like him want to be able to say this on tournament streams.
