The difference between
Al Quada is responsible
and
Al Quada is fully responsible and legitimate
is this:
Everybody else is not responsible
Which can be subdivided into
The US government is not responsible
The Russian government is not responsible
The Chinese government is not responsible
The Saudi Arabian government is not responsible
The Yemenite government is not responsible
The Iraqi government is not responsible
The Israeli government is not responsible
The Canadian government is not responsible
The German government is not responsible
The Swiss government is not responsible
The Angolan government is not responsible
...
The NWO is not responsible
The Illuminati are not responsible
The Birch society is not responsible
The cast of the Beijing Opera is not responsible
...
Oystein is not responsible
SpringHallConvert is not responsible
SpringHallConvert's Jewish billionaire mother is not responsible
Chuck Norris is not responsible
...
etc.
Obviously, we can't prove any of these negatives.
Luckily, SpringHallConvert is not claiming anything. So there is no need to prove any negative.
(I have said this many times no, SpringHallConvert ignores it. Every instance of him not proving that his Jewish concealed billionaire mother was behind 9/11 is another defeat for him. Everyboy in the Colisseum jeers everytime, only the loser, SpringHallConvert, fails to notice)
