I've been watching Coren since '97 when his show was more Agenda-like and he was more Steve Paiken-like. Towards the end of his tenure at CTS, he became more radical and a more obsessive about certain issues, i.e. abortion, religion. I never agreed with a lot of what he said, but he never made it an issue beyond, "That's my opinion" and "Let's hear yours and debate", which was always fine with me and his guests were always diverse. When he hit the airwaves at Sun, he'd lost any credibility he'd had left. His columns were always another matter of course and I rarely was able to get past the first couple paragraphs.
And yes, PM's about Krista are always welcome. She seems like a piece of work.
