I think you are missing the point. This thread was likely created because of the multitude of insinuations by the MSM, and Hollywood, that "right wing" was responsible, that the Tea Party, NRA, and skinheads were almost certainly to blame. They said, hey it is "Patriots Day", and Tax day...do the math. Now, obviously, if they will speculate for four days about that without any evidence, then don't you think they would be quick to discuss the race/religion/politics of the killer as deplorable?
When Gabriel Giffords was shot it was the Tea Party and Sara Palin's website that were immediately demonized as culprits. When the Aurora theater shootings happened, again the Tea Party link was sought. So I don't believe this thread is about pointing fingers at "them", but more about hypocrisy like this:

THIS! QFT!
