I can imagine the letter from the LW's son so easily:
Dear Abby,
My mom's second husband is a jerk. It's impossible to have a conversation with him, because he just talks and talks and pays no attention to anyone else, and he treats my younger brothers, who are grown men, like children. But my mom loves him, and I've tried to be polite and not rock the boat. The problem is that now I have kids, and he starts yelling at them when they, you know, behave like kids. If they do anything he doesn't like, he flies off the handle. My wife and I don't want our kids to be around people who yell at every little thing, so I've told my mom the kids won't be staying with them anymore when we visit their city, and she's accusing me of emotional blackmail. What do I do?
