I doubt people who are so rude on the Internet would be the same face-to-face. If I should get a nasty comment, (which I have, many a time) I simply leave the website it's on – I've got enough problems w/o adding to them; that's why all my networking is interest-based or not done.
Words like "scoundrel" need to be brought back; they'd be a lot better than the modern equivalent. I prefer "go forth & multiply" – sounds nicer & essentially means the same thing. There are a few people here (housemates, not on Mudcat) I'd like to tell that to!
If someone said to me, "be off w/ you, prithee" I'd just melt.
