Isn't Race The Only Difference ?

This is just more proof that the right-wingers treat President Obama differently than they've treated any other president (of either party). Like many other things (such as Obamacare, which was originally a Republican plan), executive orders issued by President Obama are treated as though they were much worse than the executive orders issued by other presidents. Is it because of his race? I can think of no other reason. And isn't treating someone differently because of their race the very definition of racism?
