3. we are not going to get into it, but if after all the research you have done on WTC you are going to insist that the planes brought down the 3 buildings - you have to be an idiot. you also demonstrate that you are pretty thick with you choice of words: "US blew up the World Trade Center" - US as in all the citizens? or US as in the shaded area on the map? bravo!!! you are correct!!! neither of those took down the buildings. rest well in your illusion of self righteousness and conformity
