Touché. I'll admit, it was a little 'out-of-the-blue', but so was his original post. If one doesn't wish to talk about it, then one shouldn't post anything related to it to begin with.
I don't have much problem with people doing that, as I used to to it myself. Profusely. I can't really be offended by it. As such (not trying to justify this), I have the tendency to continue this habit of 'letting people know' about things like this.
