Yes he can. Just providing information so people who might want to can spend their money any way they want, specifically on some other country artist besides this one. Personally I like to know when celebrities are spouting contrary to my values and what I think is good for the nation so I can cease to support them and their unwitting, or witting, subversion of the nation.
