So is the targeting just a ruse?
If I might propose a nexus here between the posters who appear to have been targeted, the troll may be one of our banned cretins who held the view that God created the races separately and meant for them to remain that way. There were at least a couple that I vaguely recall, who have been since been zotted.
Not so much a ruse as just the most repulsive thing he can think of. What could be more repugnant to Freepers than a vile mixture of racism/anti-Semitism?
His posts are designed to offend, and the most offensive thing possible is using the N word, which he does profusely.
Combine that with the amazingly disgusting pictures and some old-school KKK anti-Semitism, and he posts the things that will most offend the majority of Freepers, regardless of race or religion.
