Mark Dice doesn’t need to be giving anybody any ideas. I’d be surprised if it hadn’t been considered already.
“In June 2008, Dice launched a campaign urging people to send letters and DVDs to troops stationed in Iraq, which supported the theory that the 9/11 attacks were an “inside job”.[20]”

“On March 23, 2014, Dice’s YouTube channel, which had 55 million views, 265,000 subscriptions, and 3-5 million views a month, was shut down due to ‘severe terms of service violations’. YouTube restored the channel later that day after a wave of pressure came about from supporters of Dice.[23] As of July 2015 his channel has over 125 million views and more than 365,000 subscribers.[24]”
