Hey Pete,
Although I disagree with some of the sentiments you've expressed (such as in regard to the Gillette ad), I likewise agree with a lot of what you've said here.
Specifically, your points about the fraternity and sanctity of all-male spaces. I'm a huge proponent of same-sex spaces; but, I'm curious about whether you believe that gay men (such as myself) should be equally as welcome in all-male spaces?
I wrote this piece awhile back, if you are curious about my additional sentiments when it comes to these sorts of topic areas:
