I think most people, and indeed some people here have a view on PC that is entirely too black and white. It can be a useful tool I think, but not something I use in my everyday life.
I see no point in offending people unless I mean it, so in that respect being PC can be a tool to avoid that. If I try to make a point or convey a message that I want people to listen to it serves my purpose that they won't be offended by something tangential and completely fail to listen to what I'm saying. So in that way I can use it to suit my purposes. It has the added benefit that if I want to offend someone for real I still have that tool as well. I think PC allows me to operate in a discourse on more levels than if I just throw caution to the wind and speak freely.
It's the same with swearing. Personally I don't mind swearing but if it's something I want people to listen to I avoid it as not to get people stuck on a casual 'fuck'. And again, it leaves me free to curse when I really need it.
However in my everyday I'm not particularly PC as it can needlessly complicate things.
I think a lot of people see it as some kind of encroachment on their personal freedom. Bullshit I say! We are of course free to speak as we like, but there really is no point in needlessly antagonizing people.
Or in other words; a lot of people are whinging twats that can't be arsed to think before you talk.
Not quite the same feeling from those two statements, even if they mean the same. Which one is more likely to be taken serious?
Note to mods: I am trying to make a point, not to needlessly insult other users. I genuinely feel that the argument is sound. But if I am out of line I'll take my punishment.
