Conspiracy theory time. Westboro Baptist Church are pretending to be 'Anonymous' and attacking themselves to gain even more publicity.
Personally I don't think attacking the WBC aligns with the central tenets of the 'Anonymous' movement. Anonymous likes chaos, freedom of speech and expression, causing offense, etc.
Nah. It looks to me like splinter "Anonymous" groups are arising- like 'cells.' The guys involved in, say, the Iran website takedown or that security expert embarrassment operation (name escapes me) may not be involved in this at all. Just my guess, mind you.
