Brownback's using taking communion reminds me of Little Jack Horner: He put in his thumb, And pulled out a plum, And said, "What a good boy am I!"
Ostensibly he's using his personal example to underscore others face death for doing this.  But offers no hard core evidence. That people suffer for their beliefs, be they religious, political, cultural, social, etc. happens but should fall under the umbrella of human rights.  Too bad Brownback wasn't an advocate for religious liberty when the institutional church under Pius IX held "error has no right." “Though he didn’t use this precise verbal formulation, the 19th century Pope Pius IX, in his (in)famous Syllabus of Errors, set forth the principle that “error has no rights” — this, to explain why religious freedom should not be tolerated." 
Brownback's anti gay position would not extend the umbrella to cover such and others who are outside the parameters of his narrow interpretation of human rights.
