Good. Fuck them. Believe me, we aren't going to get along. Best to know now. Also, I believe in evolution, think the earth is more than 4000 years old and I support gay marriage. That offends a ton of people and expressing that opinion has the same effect on those "relationships" as saying "fuck".
You might think you're being polite. You're not. As Bill Hicks would say, you're sucking on Satan's cock, ice ice baby.
And as a matter of economic reality, I've found that the better educated, and economically advantaged a person is, the more likely they are to use words that others have judged to be offensive. "Manners" are what the servants have.
Then there's an anecdotal inverse correlation between the likelihood that a person uses the word "fuck" and the likelihood that they support dropping cluster-bombs on civilian areas. That is people go all weak at the knees if I say "fuck", but those same people are all for shredding small children: just so long as they are "non-christians". (Yeah, I'm sure you don't do that Mr No-Potty-Words HN reader - its just a general observation).
Whatever.
