>Why do these dumb fucks always target Jewish centers, filled with old Jews playing shuffle board, and never the ADL headquarters or some political target?
well... the "screw the optics" guy targeted the synagogue/jewish center/whatever the fuck it was b/c it was on a top list being congratulated about how much it had done in helping to bring non-white immigrants into the US. He essentially got the location from a jewish internet site congratulating the jewish group for their efforts in replacing whites in their own country. 

My guess would be that the target he chose was an easier target than some big time jewish headquarter mastermind location -while still being a group celebrated on harming whites within their own country by other white-hating jews.
