Do you think there's more of a "deeper" reason for the GOP to hate Obama so much

[Whateverist]

The thing about this, is that all of it can be reversed politically. When there is a Republican president in office, the Democrats hate on him and make up stuff and insults and draw hitler mustaches on him etc etc. It goes both ways.

But it doesn't go both ways evenly.  The democrats won't stand in the way of programs that help people just because the republicans authored them.  (Many republicans used to be the same way; now that would get them voted out ASAP.)

Comedians and many democrats (myself included) criticized W Bush for being stupid because he did not do well in school - which he didn't.  The man's use of English certainly didn't do anything to change the impression.  Like so many in the republican clown car he also denied the science behind climate change and held to a simpleton's form of religion.  This was justified criticism.  

He was also criticized for not achieving anything on his own merits - and he didn't.  He was born into wealth.  He was a drug addict who got religion and wanted to redeem himself by steering the nation like his daddy.  This was a warranted criticism.  

He was also criticized for being a classist.  He made no secret that he saw the 1% as his constituency.  He did plenty to weaken the social safety net - which was already a joke among developed nations.  He was fine with throwing our young military people into harms way, never having been in harms way himself because of his family's connections.  Again, deserved criticism.

Compare any of that to what Obama is accused of.  That he is a foreigner, un-American and most importantly BLACK.  It is not tit for tat.  Not by a long shot.
