I disagree. I have heard the term 'breeder' used to describe people from red states with children by liberals. I have seen the term used to disparge parents with children. It is a slam period. My children were usually well behaved. They were punished severely (spankings,no TV, grounding,long talks kids hate those) for PDBB-public display bad behavior(family term). I think there is an anti-child bias out there. I would never take a toddler to a fancy restaurant, but if a store is for families then I expect my children to be treated politely as paying customers because that's what they are.
Slightly off topic, but this statement reminds me of how rude some salespeople can be when dealing with children. Sometimes they will bypass helping them for every other customer, just because they are children. Even if they have money in hand. Guess Inoticed more as teen, since I still looked like a 12 year old. I was 18 and samplers would still ask if I had parental permission.
