Dear Mr. Black, How long do you intend to dodge the gauntlet? Ms. Walker has challenged you ["Postmarks," Sept. 3], and not for the first time, sir, to mature into the writer/editor she believes you possess the potential to be; not only for the sake of the Chronicle and its readers, but for all those exhausted by the patriarchal pedantry of the press. If you are unwilling or unable to meet her challenge, then attempt mine – offer Ms. Walker the opportunity to be a regular contributor to the Chronicle. She is consistently the freshest, most literate, unique voice on your pages. Buttressed against bullshit by years of living and the ability to cut to the quick while simultaneously salving the wound with her writing clearly make Ms. Walker far too dangerous a woman to expose your readers to on a regular basis. Cowboy up, Mr. Black! Give the little lady a column.
