Honestly this shyt is pathetic and shows me he's happy to do the LGBT thing as a gimmick for merch. If he truly believed in the principles of supporting the LGBT community, he would have declined to go there at all due to KSA's treatment of LGBT people, who literally don't have rights in Saudi Arabia. They are, literally, still beheading gay people for being gay in Saudi. Yet this dude goes anyway, takes their money, lets them tell him to change his rainbow gear that he was wearing to support the cause, then posts a tweet like that.
Take a fukking stand or shut the fukk up, you can't have something like this both ways, nerd. A real rock n rolla wouldn't pull such a shameless stunt.
