How to annihilate your own credibility

I try to read articles that are hostile to my own position in order to ensure I understand both sides of an issue. Often I learn things that my usual sources might neglect. So today when I went to Google News (a favorite source), and saw this headline:

Kerry: strange, stuck-up... and stupid

I thought, whoa. Then I saw

According to Francis Harris in Saturday's Telegraph, allegations that John Kerry "lied about his Vietnam record" are "unravelling". Oh, I wouldn't say that. Right now, it looks like the sanity of the Kerry campaign and its pals in the media that's beginning to unravel.

and again, thought "Whoa." That's so true. The media has been covering this as if it were an actual story with two sides, and Kerry's campaign response has been terrible, quibbling over the details instead of just pointing out that "hey, no one disputes that I was in Vietnam, on the Mekong Delta, in a swift boat, or that my opponent was debating the merits of intentionally blowing out his own eardrums in order to disqualify himself from service."

It didn't take Steyn long to totally blow any credibility he had, saying such things as

The other day it was CNN host James Carville, former skinhead-in-chief to Bill Clinton...

That's seven years getting tortured by the gooks, only to be mocked by some lame-o cartoonist as a redneck latrine operator.

And then, in a spectacular non sequitur, everybody with me now in a Jon Stewart WHAAA?!:

I wouldn't stand for Parliament on a family values platform because I know someone's bound to bring up the 123 gay porn movies I had a bit part in back in Amsterdam in the 1970s.

There is nothing I can say to make that any funnier than it already is.
