I guess I would say that while stereotypes are often correct, they should not be used to dismiss entire groups of people, or ignore things that maybe contributing to further perpetuating stereotypes or the situations which give rise to a negative image of certain groups.
Listen this goes for any groups that have conflict. You can see the same dismissive and condescending talk in right/left political debates, in religious/anti debates, everywhere and anywhere there is conflict. What you see is more of "your wrong" , then an environmental that says let see what we can do about this situation to make it better for everyone. Political and religious ideologies are the most dismissive of all other beliefs that we are all guilty of participating in on some level. I truly believe that no matter what side of the debate you are on there are reasonable and logical arguments being made, however it is lazy to subscribe to a blanketing ideology without question. In my opinion, I think many people are increasingly lazy in formulating their own opinions and trying to find actual solutions to problems.
Our country is facing many challenges and they are effecting a much broader spectrum of people at the moment. One can here the dismissive tone that so many justified with race being applied to larger and larger segments of out population. It was wrong when it was race based, and it is wrong when it is economically based. Just because One can now see people of all colors struggling it does not diminish any persons struggle. This should having touched so many in the recent years, and should be used to understand what in many cases has been going on to certain groups for decades. The danger is that it can be used to further divide groups.
