Here we have a woman who undoubtedly has more than a few management skills, and who tried politics for a while but is returning to the business that she ran successfully for a number of years. There seems to be a double standard here. People are calling her a bitch, a whoore, etc. presumably because she had relationships with several different men. Belinda Stronach is single. How many guys in her position would be celibate? Not me.
It's because some men who aren't as successful are envious, and have to find a way to put down any woman who is more powerful than they are. Like Peter Mackay, who only got where he is today because of his father and Brian Mulroney, and generally has more than one girlfriend on the go at a time, who had his little feelings hurt. So all the old boys had to act like "big men" and be ignorant and insulting.
Typically, that says much more about the person using those words. For example, those who call her a b*tch, even in this thread, are revealing an awful lot about themselves. And it isn't pretty.
