Except you very rarely have enough information to make informed judgements. It’s inherently dehumanizing to assume the limited information you get from say a news article is all that’s relevant because it treats them as cardboard cutouts of actual people.

It’s easy to see a pregnant teen and think poor thoughts about them without considering if perhaps they are older than you assume and married or they got rapped etc. Read about a convict and perhaps they did something horrible or perhaps they’re wrongly convicted, you simply didn’t know.
