It should bother you and make you consider that no matter how much us white "racist" Trump supporters disliked obama and his anti-American politics, I would challenge you to find one posting on this site where any of us advocated the assassination of obama.
I *think* I can say without reservation that there are few who despise obama more than myself.
Having said that, I have muttered a few times that I am completely surprised the SOB made it this long without someone trying it. But advocating for or even wishing it upon another human is below the belt and downright despicable. Sometimes I'm surprised that even these wack-job, violent leftists mutter those sort of words... but here we are.
