Well, lots of big fans of the conference replying to Fox's tweet here. I've copied some below for "balance" on the thread.
"No way anyone who actually watched the conference thought that. He very calmly destroyed them. They are crybabies."
"Loved every minute - great box office and base morale building"
"It was refreshing and awesome. Do you know how many of us want to do that on live TV. A lot right now. Good for him."
"i loved it! He has made it clear he is there for us not to make the media happy!"
"The media was expecting the President to cower at the press conference. Didn't happen!"
"how refreshing to see the media called out after 8 yrs of puff piece interviews & softball questions for Obama & HRC."
"Media is unhinged and disturbing. Was great he gave them and us time in a very busy schedule. He will not appease and bow."
"he told the truth the mainstream media is the lamestream media their worthless lies they should be unplugged"
"FANTASTIC & SPOT ON! Trump speaks to me"
"He was himself, not some high falutin pc lovin politician. The people love this."
"love it hopefully President Trump continues to communicate to the people like this and twitter I myself prefer it"
"brilliant and long overdue! He was confident, relaxed and on point! What's unhinged about that? They just won't stop! Unreal!"
"it was great to see him in his element. He even answered questions from people he didn't like."
"LOVE MY STRONG ARM LEADER-NO ONE CAN PUSH HIM AROUND-NOT THE PRESS-HE CAN HANDLE ANYONE"
"this will create a movement all over the world. People are not stupid and want fairness"
"The so-called mainstream media is unhinged and disturbing. They are jeopardizing the 1st Amendment."
"I called every freaking awesome move he explained to them they are nothing and he was nice about it"
"He hit it out of the park! No political speak, no ego, spoke from the heart!"
"I thought it was fabulous! They are the unhinged! DJT is moving like a tornado and they are in his wake!!"
(I really am curious about the number of Trump bots - some are accounts with numbers in their usernames and low-follower numbers, suggesting fake, but then that could be a real person too stepping into the grand world of social media, so how would you prove it? And as a random person, would you take time to verify or to think "ahh, x million fellow fans, they must be right".)
