I think it's really easy to get caught up in the 'checklist issues' and forget that there are people behind them, who ostensibly are making the best choices for their families with what they know to be true. It doesn't mean I can't be disappointed or that I have to be bff's with people who parent much differently...but it's simplistic to think that one part of a person is the sum of that person. We're all flawed and nuanced and when people share some of our philosophies, it doesn't mean that they are just like us.
The people I've disagreed with most have made me think the most and hone my own philosophies and beliefs. The world would be a terrible and boring place if everyone was just like us.
