I would like to see just what kinds of statements these two made against U.S. policy that got them banned in the first place. Also, it appears as though one of them gave money to a charity that funneled it to Hamas, an organization which the U.S. government has designated as a terrorist organization. How that is not supporting terrorism, no matter what the donor says, is not clear to me.
There is just not enough information in the article to be able to say whether or not I'm comfortable with it. I'm sure I myself probably hold some views about the Palestinian issue that some people here would find disagreeable, but there is a lot of grey area when we're talking about disagreeing with U.S. policy. I would hate to think that someone who openly advocated for terrorism would be welcomed into the country despite that support just because we want Muslims to think we're nice. I don't really care about Obama's "new relationship" with the Muslim world or whatever. I don't think we should be so servile. If it is all about mutual respect, let's see the Muslim world demonstrate that respect just as we try to by allowing Muslims to build mosques here, preach peacefully, gain converts, etc. Until then, it's really not mutual and therefore should not be used as the basis for making these kinds of decisions.
