As a veteran whose served this country, I acknowledge the rights and freedoms of EVERYONE to express themselves, that's what makes us the greatest country in the world. I'm not sure how I feel about this person making some sort of message by dancing on the graves of those who made the ultimate sacrifice.

So you and others on the authoritarian right would do what, exactly – have someone arrested for dancing on a grave, subject that person to criminal prosecution, make dancing on graves ‘illegal’; what’s gone too far is conservatives’ desire to compel conformity and punish dissent.
