Hello. I know all of those people and organizations because I have been tracking them down for years now. The Nodo50 people have always supported terrorism of any kind. The same goes for IU. As for that group belonging to the ISM, is the terrorist organization eta itself. These terrorists have at least another ISM organization (askapena). ETA has had relations with hamas since this organization appeared in the terrorists scenary. At that time, I was living in the basque region, and eta people invited some hamas thugs there. I saw it with my own eyes. They keep the relationship. And what a coincidence, the day of the Madrid bombings, some eta people and some hamas members were in Madrid together because they had organized a lecture to be given by a hamas "doctor". Do you know where I saw the advertisement? On the nodo50 website. As I said, some people of nodo50 write articles in eta "newspapers". I have a couple more posts that have not been published. I am trying again.
