Plenty of people knew about Alex Jones. He had claimed that 9-11 was an ‘inside job’ almost as soon as it happened; and if I recall correctly, that’s why we were not allowed to post links to his stuff here.
The controlled demolition of Building 7 proves it was an inside job.
As for why Infowars is no longer anathema on FR, that was a management decision by Mr. Robinson. I suspect it is because the conservative community has moved away from the Bush/Dole/Romney/McCain Republican Party and the older consensus of National Review and the AM talk radio of 10-20 years ago. The rise of podcasts and blogs and the effect of Trump transformed the conservative media world.
So ? Plenty of people here on FR and other websites said the same about the TRUMP ASSASSINATION ATTEMPT.
