I have to say that anyone who supports hamas, hizbollah, isis or any other fanatical, extremist, religious group deserves to be on a watchlist.
I have no list myself.
Think about these things. Did Israelis carry out the Manchester Arena bombing? Was it Israelis who beheaded a Manchester taxi driver who was simply taking aid to the middle east? The answer in both cases is no.
Is it Israelis who are complicit in the child grooming scandal? I don't think so.
I could go on
I am not particularly religious but if I had to be I would not wish to be associated with a religion which carries out torture, rape and murder.
Think about this.
