I try very hard not to block people. I really do. I can tolerate disagreement, argument, and even a fair amount of foolishness. But when someone shows up with a chip on his shoulder and a disposition aimed mainly at stirring the pot, and when he offers nothing that helps anyone understand the matter more deeply than before he arrived, such a visitor becomes tiresome. Even further, if a person continues to perpetuate the lies told about Charlie Kirk—the lies that helped make the hatred that got him killed seem permissible—that has become an absolute line for me. I have no obligation to keep handing a microphone to slanderers, no matter who they are. Again, I can tolerate disagreement. I can even put up with trolls for a little while. However, I am entirely uninterested in pretending that slandering my friend is conversation.
