Why would I prove him wrong when I can just report him, censor him, dox him, threaten him, harass him, attack him, and destroy his life for saying hate facts that hurt my feelings? Twitter will side with me. The police will side with me. The media will side with me. His employer will side with me (after my targeted harassment campaign). The government will side with me. And ultimately his opinion will disappear and therefore I will win by default.
