One of the things about living in a "free" society is that we have to deal with other peoples idea of correct or right. Too often people cop a position and "inflict" that position on others. Is the position that pets are livestock, property, unworthy of human attributes any less an infliction of ideas that the person dressing their poodle as a ballerina and walking through a store?
Our society needs more tolerance. What does it matter if someone is walking down the street with their pets in a stroller or even in a store - as long as they aren't disruptive or dangerous.
Choose your battles, we have so many more important things to worry about.
