That's a good point. But then, if you were a considerate human being you wouldn't talk at the theater, text at the theater, play games on your phone during the dark parts of the film, talk on the phone, turn off your ringer, scream things at the screen, stomp on people, bang seats, and do all the entertaining things that go on in everyday life at the theater that aren't kid related.
I agree, if you can get a sitter or do not bring your children to such things. But let's not say that it's those darn kids and their parents that are the only cause of distractions and disruptions. A lot of time, it's what people are willing to overlook or disregard. People are less willing to forgive other people's kids (I left mine at home, I didn't come out to hear kids, I hate kids, etc) than adults doing the same or worse.
I think if you look at my post upthread you'll see that I'm not willing to overlook or disregard anyone complicating my movie going experience.
