Yes, but they are easy to spot. My son brought a feminist sort of young woman to a Shakespeare in the Park with us. She was so mouthy and sarcastic with him, put him down for not having quick repartee (he was homeschooled) -- he hated being with her. We had a great discussion with him about what had happened, what it showed, how he felt with her, why to avoid her and her ilk. He learned a lot. I won't hesitate to do it again, if needed.
Hate that the son had to put up with that in front of his parents,but, when opprotunity presents itself so neatly wrapped we must rip the wrapping off and reveal the treasure inside for our loved ones. And by the same token, they for us.
