All-too-common occurence illustrates a problem I encounter pretty much every week: A reader contacted reporter Randy Covitz and me about Covitz' story last week about gay athletes, after Larry Johnson's recent suspension for using the words "fag" and "faggot" on Twitter and while speaking to the media.

The reader's point was weak, but defensible: Shouldn't the story have quoted someone who thinks using those epithets is no big deal, and that homophobia is justifiable?

My own opinion is that the story did include a variety of voices, including Jayice Pearson saying he doesn't think Johnson meant it literally, and that the locker room is a place where insults of every stripe are common. Tony Dungy said, "It hasn’t been accepted. It’s a hard thing. It was not something that was talked about in the locker room when I was at Minnesota."

Should Covitz have found someone to express explicit bigotry? I fail to see the journalistic value there. But again, it's a defensible question.

Here, though, is where my reader really went off the rails. In two follow-ups, he launched into a breathtaking, spittle-flecked denunciation of gay people, whom he called "gross" and mentally ill. I ended the conversation there, as I don't care about anyone's bigoted personal thoughts -- and his rant was based on almost total ignorance of the science, medicine, sociology and history of homosexuality.

So here's my larger question: In my opinion, this reader's showing his true motivation behind his initial point makes me far less willing to air it. This is an extreme example of a phenomenon I deal with often.

And while I have to be honest that I more often encounter such intolerance with traditional "conservative" points of view, there's no shortage of straw men, untruth and invective from the left too, especially in matters relating to religion. The single most horrible thing I've ever heard a reader say was a personal insult of religion editor Helen Gray, whom he was mad at because she ran a "Faith Walk" column by an evangelistic Christian.

I don't think I've ever intentionally given major consideration to a point brought up by someone with not-so-covert bigotry as a motivation -- but should that even be a deal-breaker? After all, if it's a fair argument, it's a fair argument. Or do you think the questioner can legitimately poison the well in the broader context?
