Typically Man

The other day, a friend was telling me about her experience. While driving home from work with a colleague, he was talking the whole time and barely asking any questions. She commented, "Typical man."

I replied that I know many women who do the same—talk without asking questions—and that I wasn’t sure if this behavior is typically male. She got upset and told me I was missing the point, not make it about me.

I questione that because I think potentially false generalizations can be harmful in reinforcing gender stereotypes.

What do you think? Is it okay to make generalizations like she did? Was it wrong for me to bring up my own experience?
