Umbridge and Blood Lines

I know this may have been covered, but I have been away awhile.  

I was wondering about that horrible punishment Umbridge had for 
Harry, the quill that wrote lines in blood on the back of his hand.  
Does anyone else think this is symbolic (yes, quite elementary) of 
Umbridge's preference for purebloods and willingness to punish half-
bloods and mudbloods.  If so, how far would she take this?  DE?  
And, what might she know about Fudge?
