Illuminattile, forget discussing who's important than who. But as the 'superior' being, its our job to show equity and justice to those that are weaker than us (animals). Just because we have power over them to a certain degree, doesn't mean that we can use that to our advantage regardless of the suffering and injustice we do to those that share this planet. Intensive farming is borne out from capitalist greed, it doesn't matter who gets hurt or what gets vandalised, as long as the big guy makes money. There are absolutelty no ethics involved to big business. Although I don't advocate reciprocating a wrong with a wrong, its hypocrytical to chastise PETA for their actions when the people they are targeting are doing what they're doing.
Humans (to me) are much more important than any animal in the world, but that doesn't mean that I oversee every human injustice against nature and its inhabitants just becasue a 'superior human' did it. People have to bear the burden of their injustices at some point. to use the argument, yes but we're doing it to animals and they're doing it to us (humans) is redundant.
Ofcourse 9/11 is mush worse than intensive farming and ivory hunting, but to compare them two distracts from the animal rights issue in its own right.
There's also reports of a media propaganda against these types of organisations funded by big business to make them out as evil and distract from the real issues. Don't believe everything you read.
