Tim Pool is a person of mediocre intelligence doing his best impression of an intellectual. Anything that gets people to stop trusting mainstream media helps our side. They have done an incredible amount of damage, and every person who stops watching television or reading the propaganda press and starts thinking for themselves is a beacon of hope for our dying civilization.
"No matter how much you hate the mainstream media, it's not enough." -Glenn Greenwald
What Tim does is basically what Rush Limbaugh did -- gather up the news that the main stream media, (or in Rush-ese, "lame stream media") puts out. Then he looks for the stories the corporate press isn't giving any attention. Rush had a knack for telling us what the news was days -- sometimes weeks or months -- before it actually became "news" that the networks bothered to cover. Once the light was cast on the story, it became difficult for the Left to ignore it.
Tim does that to a large extent, but he also brings on people of all political leanings, including diehard progressive liberals. At least, he does that when he can find someone willing to discuss topics of interest. He's even had Cenk Uygur of The Young Turks on his show where he let Uygur give his thoughts, opinions and political positions in full. Uygur was a presidential contender then, but he's since closed his campaign doors.
There was one Progressive brave enough to go on the show, and the pure ignorance and bias the guy spewed was an affirmation of the leftist stereotypes we almost all tend to believe. A lot of people commented on the show that they can't believe Tim would give this person a platform to argue for such stupid opinions. Tim responded that was the whole point. He's open to discussing issues with people holding opposing opinions and viewpoints, and he leaves it to the audience to judge for themselves whether the arguments sway them.
I think many people who dislike this show or that person tend to only see the sensationalized videos or clips that center around a given topic.
Tim isn't part of the mainstream media. He's the exact opposite. I think his success is in part due to Rush's departure, which left a pretty large void in the Conservative talk show lineup. He says he doesn't identify as Conservative, but the Liberals have gone so far left, he's become Conservative just from the "shift" in political leanings.
