I agree that the website seems to be radical left, but that doesn't justify posting pics, an act which is clearly intended to identify the individuals depicted as guilty parties.
It's an irresponsible, dumb thing to do.
I don't see why, they have their website where it can be found, I have websites also with pictures but I didn't advertise. They all seem to be quite out in the open with their hatred of Israel and of the USA. They want their political leanings to be known. Anyone linking to the EZLN which is an international terrorist group deserves any publicity they get for it.
