I think this is very important research. I am glad you are doing it. I would also add:

Floyd Corkins in 2012 sought to intimidate those opposing gay rights by going into the Family Research council ind DC with a gun and back pack full of chick-fil a sandwiches. He planned to compel victims to eat the sandwiches as they lay dying. Corking had a list of additional conservative sites he planned to attack provided by the SPLC.
Thank you. Will add.
