When you point at a piece of shit and say "don't step in that" are you 'slamming' the piece of shit.
You mistake legitimate criticism of a Universally disliked person as 'slamming.'
And you mistake a group "legitimately criticizing" a sitting president for a genuine show of unity.
Do you really think a funeral was an appropriate place to take political jabs at the president?
McCain refused to give in to the birther movement because he respected his political opponent. I doubt he would have ever approved having his death politicized in such a way. He never deigned to such a level.
But you will. His daughter did.
How disgusting.
