I didn't get a chance to see the post since it was already deleted so I can't comment on that. But I can comment on Dovster's style in general as he is a regular and valued poster on the DL forum. He is at times irreverent and outspoken (BTW, so am I) but always entertaining, humorous, thought-provoking and very helpful to all his fellow posters whether regulars or newbies. The Dovster you describe is certainly not the one I've come to know. And, yes, I do catch many of his posts in the OMNI forum as well.
My two cents worth on a fellow DL forum poster who in just a few months has become an indispensable part of our forum.
