Using the term "hacktivist" for Anonymous is a little much. They are nothing more than a digital terrorist group. Power corrupts and we can see it has been corrupting Anonymous for awhile now. Anyone that pisses them off in the slightest they take offline using D.o.S attacks (which btw takes very little skill). Any script kiddy can find the tools to do this and it's pretty easy to hide it in a file and get unsuspecting users to install it.
It reminds me of when I was 13 or 14 and I used to use the old win nuke/smurf attacks on people that pissed me off. The only difference is that these guys are adults and they still think that this is going to solve anything.
