Yes, infact if you look through that website there are many lectures given by many different authentic Rabbis, trying to spread the message. They say the acts of certain zionists are giving a bad name to peaceful Jews worldwide!
I can believe that, as we had Jewish neighbors, and we used to pass food to one another. Whenever we had a BBQ we would send some over, when they had other things they would send it over as well. We kept in contact and our children used to play together. Decent folks.
