No, putting them together is correct. If you'd done a cursory search for connections between it and the MB, you'd know this. Nothing Texas is doing has to work on me, I've been aware of this connection for years.

There was another great link about this that I saw recently, and I thought I'd bookmarked it but apparently not.
As for my "most muslim countries" misstatement, solid hit. It was late and I wrote that in a hurry. I meant most middle eastern countries, and specifically the MB. The Egyptian Military overthrew Mohammad Morsi because the people had just elected an Islamist government run by the MB, who have long been banned there, for example. The fact that they're widely known to use CAIR as their US front group, moving money through subordinate entities into our political races, they're an honest to goodness problem. I encourage you to look into it on your own terms, because the more you look, the worse it gets.
The best part about this to me, who served with the Marines, is that the whole lot of 'em are so gay adjacent that Sgt. Morgan could very plausibly be straight and that other guy is just one of his Marine buddies who wasn't on the deployment with him and the photographer just made an assumption.
"The Navy is the straightest bunch of gay guys you'll ever meet; the Marines are the gayest straight guys" as the saying goes.
