My habits and experience are the same. I have some sympathy for the young campus feminist, however. She has recently come to realize that some aspect of her every social interaction with men between the ages of 14 and 68 is "hmmm, I wonder what it would be like to engage in coitus with this young woman?" She hasn't yet realized, however, how best to use this fact to her advantage. So, it's easier for her just not to not have the "dude held a door for me" interaction.
