ISIS terrorists have been financed by such people as the ones you have pointed out through taxes. Where the dollar goes is surely not under any control, and I do feel sorry for the American tax payers. The ESL sites you suggest are a helping hand in monopolizing the western, American in particular, education. Scores of foreign students, out of whom few can use the language they are studying in, speak loudly; many of those students have gone through companies which sponsor people like Dave. We belong to filthy species that have not figured out how to live yet.
