So unable to handle a thing different to what's in your head, because you haven't been thinking critically. Because you've only engaged the culture in a "consumerist" way, absorbing talking points, and getting trained that that when you push a little button that says, "You're a Nazi"--or "You're crazy"--then the "annoying ideas" will be silenced. But none of this is thinking.
And unless you think, then you are not equipped to handle online discussions or deal with information different to what's in your head, because of course you will want it to be silenced and censored.
