Everyone is judgemental. Or, perhaps a more polite term would be ‘discerning.’
We make decisions on a regular basis about the people we meet, the situations we find ourselves in, and make choices based on the information we have available.
Some judgements are quicker than others, some change over time. It’s human nature, and as everything about being human goes, can be good and bad, mild and extreme.
I have certain ‘do not cross’ lines in my head. If someone does, I’m out, and there’s no coming back from that. I suspect most people have similar attitudes (not that everyone’s lines are the same, of course).
Somewhere along the line, being called judgemental became a huge insult, but the truth is, we need to be able to judge other people in relation to ourselves/families in order to make good decisions. “Is this a safe person? Is this a healthy person? Is this a good dynamic?” etc.
