I can understand living with the condition can be a real hell if people around you don't understand it.
If you don't have it, you don't even have the slightest clue as to what it really feels like to deal with every...single...day... of...your...life...24/7. Varying degrees of this disease can determine whether or not you can function normally in society or not, or even at all. Uncontrollable swearing is not, by any stretch of the imagination the only symptom of it. No, it extends far far beyond that.
As someone who was diagnosed with it as a teenager, I find the humorous aspect of this despicable on every level. Fortunately for me, I was able to outgrow this by my mid twenties, but for many people I know and have known in my youth, have not outgrown it...and I still have not forgotten the hell I went through as a youth, trying my hardest to control the uncontrollable urges this disease brings upon it's victims. The harder you try to control it, the stronger the urges get, until it explodes. Try acting like you've got this disease for one day. I'll bet every penny I have, that you won't make it ten minutes before you give up.
if this mod really exists, use it...or not, but don't try kidding yourselves, this isn't about role-playing purposes on someone who has it. It is only so you can amuse yourselves at others' expense...other people who have a real condition, and who's only wish is to be able to live a normal life without these urges, but cannot do it because they are too powerful to control. Medicine can help, but it is by no means a cure.
