From a different perspective...

I think you [generic you] have judged others when you expect them to judge you, and just sit around waiting for an event to happen that proves it. You've made an assumption about their character without any evidence.
i think when you read about (or cop yourself) negative comments on everything in life, you kinda expect that BF is just one more thing for someone to say something about.

i have chosen not to spend time around certain members of my family now that DD is older because they ARE judgmental - they've not been in a position to say anything to me personally, but i've watched them say it to another family member, and watched how she hurt - and the fact that they just didn't give a damn how much they hurt her

so yeah, maybe being on the defensive is not giving the general community at large the benefit of the doubt - but at the same time, when you've been criticised by the people who should be most supportive of you about every other aspect of your life, it's kinda hard to have faith that those attitudes are limited to your genetic line!
