The left has thrown around the charge of racist (once considered truly terrible) so often that it has lost all meaning. On a blog, one leftie attempted to defend calling one a racist, who was defaming Islamists. Hint, dufi (is that the plural of dufus), Islam ain't a race, its a religion. Are all atheists racists if they say something against a religion -- NO!
It has become so vapid, that T-shirts with the logo "A Democrat Called Me A Racist" are common at conservative conclaves -- very funny when worn by Asian and Black conservatives.
I say Hillary stumbling over the term radical Islam, preferring the term jihadi -- big mistake. A number of Muslims take offence to that -- claiming jihad can mean inner or outer struggle/ I suggest the best terms are Islamist and Islamicist -- both used in the ME by Muslims to describe their crazier brethren.
One could almost imagine a present day Democrat calling soldiers in WWII Germanophobes because, shortly, they were going to kill a great number of NSDAP, who also happened to be Germans. One can also imagine those GIs beating the snot out of such Democrats.
