How do I put this, the fact that a platform may be used by unsavory characters in some specific capacity and context does not affect normal people who use it to communicate with friends - which is what chat apps were designed to do. People use discord to talk to their friends while playing games. They use WhatsApp, signal, telegram and so on to text with friends. At least that's the primary usage. Now if one were to venture out into the wild and start engaging with strange animal fuckers in obscure channels etc, that is something that doesn't play into the average user experience.
