Here are a couple of comments which I have transferred from one of u/winn 's other posts which was deleted:

Also, my attempt is to keep focus on this, especially since we now have a parallel Obama narrative deployment (the one about him being a "thug") in an obvious attempt to flood the zone and prevent the gay story from going too viral. They need to keep Obama in the black population's good graces as much as possible. The fact that these memes came in hot on 8kun one after another also helped fuel the 3 post bonanza. Furthermore there are few new posts made on Saturday AM. Fourth, you know it's fucking dank

Kek, the past week or so sure has seen a lot of Obama news seemingly out of nowhere, and it's getting closer to the time when they would have to roll out big Mike if that's their plan... All I know is with this gay stuff coming out we have a chance to put a big dent in whatever black support the Obama name might carry, the gay agenda hasn't permeated the black population nearly as much as other groups

Really good points about why these memes are appearing.
