If it is in fact all lies etc, then sure. But, I do think this is often exaggerated, and a lot of times "start a conversation about incredibly nuanced topics" might not be so nuanced and in fact hateful, look at dog whistles for example. That there is no tolerance for intolerance is kinda necessary (paradox of tolerance). Idk the case you are referring to so can't say if that's relevant to this situation or not.
I do strongly disagree that people suck. My experience with people is that generally they mean well, try to live their best live, and wish well on others, even if they might disagree on some things. A good test is to just think about the people you interact with day to day in real life, not tv, not twitter, not whatever. That's reality.
