Off topic rebuttal:
There are alot of French names that are used for either gender. Are you implying that because a Frenchman has a name such as Michel or Jean Marie that he is effeminate? If so, I think you should tell that in person to a French Canadian - if you have the courage.

Being Canadian, it'd almost always be perfectly safe. Either no offense would be taken from the idiot square-head, or there'd be several chances to appologize. Aren't we the only country whose atheletes shake hands after the sporting event? Oh heck. I admit it: I like curling better than hockey.
