It's funny, you have a conservative MP's aide (not the MP himself) caught saying something dumb and people are calling for the MP's resignation. Then you have another MP who has to step down due to a comment that he made on a blog that most people probably wouldn't find offensive. Critical yes, dumb yes, but I wouldn't call it offensive. In both cases you have the Libs and the NDP screaming for their resignations.
Now compare that to a guy like Garth Turner who basically insulted the both the province of Alberta and Quebec all in one fail swoop and who writes some pretty inflamitory stuff in his blog on a daily basis. But thats ok of course.
