The Simpsons S15 E08 Marge vs. Singles, Seniors, Childless Couples and Teens, and Gays

"Just a product of society that's lost its good manners."

When a group of singles, seniors, childless couples, teens and gays band together to protest having to accommodate families (including paying property taxes used to teach children they do not have) after a riot at a children's concert, Marge takes up the cause for the families, with some help from Bart and Lisa.
