I don't know if ignoring lies is necessarily a problem. Because what are the realistic chances that anyone responding to non factual information, is responding with factual information? Probably pretty low on the net if we're being honest.
That said, yes, we absolutely cannot ignore the toxicity in its entirety. Ignoring it entirely is how little old ladies at church bible studies wind up dead. There are certainly classes of toxicity that it's just military sense not to ignore. Religious and ethnic extremism, etc. Basically anything that is going to cause issues with physical violence. To my mind, violence is the line.
