For someone like your little troll, it is inconceivable that a woman, not only wouldn't want to get married, but can have a meaningful, and fulfilling life outside of marriage! He is thoroughly unable to imagine any way of thinking about the world outside of himself.

People tell you who they are, and what they think is important, by how they insult you, (since they don’t actually know anything about you), and all that insult showed was how important HE thinks it is, for a woman to get married. He cannot seem to differentiate the things he thinks are important, from what other people prioritize. He thinks its important, so therefor, any woman must think so too, and thinks he can make some kind of pointed insult by calling it out.
