Edit: I probably should've made this clear at the start - this is a hypothetical question. I posted it to see what other people on TRP thought, and tried to do so without including my opinions on the subject and possibly influencing other people's answers.

So let's assume that I have no interest in having children of my own, or that I am for various reasons unable. Is there any reason why I should not include single mothers in my pool of potential dates, assuming that they pass all other entrance criteria?
