Our intellects should be eager to classify what might at first blush appear to be "all members of the same set".  

In fact they should be very active in seeking to understand differences, similarities, contingencies and so forth.

I won't be brow beat by anyone for wanting to understand how members of a set differ.

My hypothesis of groups is likely quite right and reasonable...who is in what category isn't my business..and what proportion are in which category isn't known.   The categories do exist however.

Your suggestion is anti-intellectual..and the trailing part of is just nonsense.  

Some people use injuries as strange badges of honor in order to garner limelight.
