who are we to judge?

I get so frustrated at people that make judgement calls about what someone should or shouldn't do based on their own limited perspective. I just don't get it! People throw around ideals about how someone should or should not act, yet they make no real effort to understand why that person made the decisions they did. I recently came across someones amazingly narrow minded veiw of the victims of Katrina...they had the nerve to postulate that we should focus on the victims that had "LISTENED" to the warnings to evacuate before we focused on the victims that "DIDN'T LISTEN?" to the warnings. That whole premise assumes that the victims stranded in new orleans and other areas in katrina's wrath "ignored" the warnings to evacuate... so where does that leave the people that were not able to leave because of transportation, health, money, or a myriad of other barriers to evacuating? What that statement is really saying to me is that we shoud focus on the middle and upper classes that had the (means) to evacuate and leave the poor festering in the filth that they created by their poor choices...RIDICULOUS!
