Kennedy deputized the Alabama National Guard to force Democratic Governor George Wallace to accept Black students at the University of Alabama.  It sometimes is very wise.   

So now you call conservatives racists?  The second most liberal president in the history of the country (after Wilson) Democrat President FDR was the one "rounding up brown skinned people." He impoverished and interned Japanese American citizens during WW2.   

You are consistently wrong but continue to post your unsubstantiated and hurtful opinions anyway.  
To be a liberal you do not have to be ignorant and misinformed but it sure makes it a lot easier.
