So this just happened

I met a guy about 2 weeks ago that has 3 children and I myself have 2 precious babies. My son who is 8 and my daughter who is 5. When I told him that I had children he turned me down and said he preferred a woman without any. I walked away but I also TRIED to respect his personal preference and understand his opinion instead of being biased. But it didn't sit right with me. In your opinion, is it fair for a man with children of his own to turn down a woman that has kids also?
