if things aren't working out in a conversation the easiest way to stop it is to not say anything. if people arent changing their response, simply stop talking about it and ignore anything related to it that they say
on the internet the word autism is equivalent to stupid/bad, so using the serious disorder definition is not something you should do unless the conversation is explicitly about real life autism. here the point is that despite being well made, the two universes/themes being merged here is a stupid idea, which i agree since the tone of tf2 is not nearly as emotional, cute, kind, or invested as the tone undertale established.
