It's only a personal attack* if I take it personally. And I don't. Ever. I was called worse things than that all day at work, and that was by people who like me, usually.**
Years ago, someone at work who didn't much care for me (shocking I know) said some bad words, actually rather creatively. The steward who had running problems with this guy (and face it, he had to be a jerk if he didn't like me) gets all hot to trot that he's going to write him up (and the fines are heavy) for 'personally insulting' me. But I stepped up, and with blazing solipsism firmly applied with keen Jesuitical logic and said: "It's only personal if I take it personally, and I didn't and don't. And its only an insult if I feel insulted by it, and I don't. And I want you to make that the first line of your report - that I do not feel personally insulted." So much for the report. And while I don't know about 'twit' I'm pretty much sure that from some angles that was a total prick move on my part. But, years later now, that guy is great with me. When he works for me, he works. I've even heard that he's been caught defending me, or at least saying nice things about me. He hasn't dashed out to get girls sox with pink stripes to wear to work as a salute to my sartorial splendor, but oh well. Whatever small temporary satisfaction I might have gained from his 'punishment' (and the fine goes to the Union, not to me) was far outweighed by the long term gain of changing my status and relationship with this guy.
In the end, my sense of self-actualization trumps whatever vocabulary he would choose to employ anyway. Once you know that the opinions of others does not, and can not, change who you really are, then it's pretty easy to get over the hump.
And, I'm also pretty sure that what Scoop was saying was a prick type statement too. A zen trickster prick perhaps, but a prick none the less. That's why I love it, use it and have had it follow me around for 30 years now. It's not that the news is bad, the news is bad because your not doing anything to change it and make it better. It's not the fault of people doing 'bad things' it's really mostly the fault of good people doing nothing. And good people hate hearing that because they know it's true.
* - It's not even an attack, 'attack' is a very strong verb, very deliberate and with physical manifestations. That was only an insult, and only a grazing one as I find the use of the word 'twit' to be very British and Monty Pythonesque, and outside of Monty Python I never hear it used. It's kind of quaint and archaic to my ears and not something that anyone on the West Coast would ever say.
** - I always thought I should be in the Guinness Book of World Records because I bet the word 'bitch' has been used toward me more than toward any other male-bodied person on this planet. They think it's an insult, I think they're just pissed that I got my way, and they didn't.
