Are All Men Dogs? | The Writer's Treehut (wordpress.com)

Here's this one woman's comment that I found that tries justifying the term for men:

"Because more men than women are dogs. Take that to the bank. This has been my experience. I have beeen in circles of academia, sports, health care, middle america, and marginal existence, to name just a few. They pretty much are all the same…self centered, narcissistic, and think the female population is there to serve them, in whatever way they want. I dont know how they can stand themselves. The men who I have met that are not like this are akin to a fresh spring in the desert…that rare."
