Husband undermining my parenting

We took our daughter to a pumpkin patch. She's 8 and they had all types of activities there. There was a hay ride and we waited in line. There was a father in front of us and a kid around my daughter's age. I think he may have had some type of disability because he had those giant noise cancelling headphones on. Well when he was getting on my daughter went and yanked him off pushing him to the ground and said "LADIES FIRST!" I child started screaming on the ground and I made my daughter get off and apologize and told her that she can not go on a hay ride now. When my husband found out what happened he laughed and said "Well he should have been a gentleman." And winked at our daughter and said she did nothing wrong and don't listen to Mommy then took her on the next hay ride. I told my husband that I don't appreciate him undermining me. He said that my daughter was just standing up for herself and isn't that what I should want. I said she was being a bully and he rolled his eyes at me. I'm really annoyed with the whole situation
