Is it bad to recognize there are differences between groups of people?

Not if one group were axe murders.....:(D 

That depends on if the differences are actual, or stereotypes.

For example, people have different blood types ... and it could be lethal to give someone a transfusion of the wrong blood type.
On the other hand, it could be lethal to NOT give someone a transfusion just because the other person is of a different ethnic type.

We would have a really hard time classifying anyone in groups if there were no differences between them. It would also be extremely difficult to learn much about ourselves if we can’t recognize our differences.  

It is a natural function for our minds to seek out patterns in what we observe to aid us in understanding the world around us. Being able to discern friend from foe, familiar from strange, strong from weak, is an invaluable survival skill.

In what scenario could this be a bad thing? This post was edited by Don Barzini at July 20, 2018 9:19 AM MDT

The problem is not differences, the problem is bad manners.

It is important to have good manners. Even people who don't have good manners consider it important to have good manners.

Unfortunately, there is no point in a child's upbringing where somebody teaches good manners.

Something very odd that I have noticed: I often mention that schools really should teach acting because we judge kids by the way they act. There is almost always one person who says something like "There is no reason to prepare all kids for a career in acting." 

It's never bad to recognize differences.  It's stupid to pretend they don't exist.

Recognition identification is bad when used for discriminatory oppression. A practice common place in Luciferian society under the Latter Days Beast System.

I think we do that quite naturally and not just differences but similarities.  And it is all part of our survival and adaptive mechanism.  But where we go wrong is when we attribute a certain outlook or certain behavior or manners to ALL of a certain kind of people based upon just those we have come in contact with.  Which can be again quite natural but is judgmental and can be exclusionary. 

Personally, I think it's respectful to notice differences, we aren't all the same, and we should be valued and our differences celebrated .. but definitely not hated, feared or used to unfairly target anyone. 

i dont think so
