Your pictures prove nothing. Obama is photographed thousands of times a day. Simple random chance would show him striking gay poses in over 90% of them.
The second one is just pure joy, maybe like a ballerina ...or an effeminate bi-racial community organizer mincing his way down the steps from AF1.
Then too, there's that throwing arm that I'm sure brought plenty of ridicule in high school...
But like I said and we both agree... pictures mean nothing.
