&quot;<i>The person who happens to like sci-fi isn&#x27;t motivated by excluding anyone; they like it because they like it and will share their enthusiasm with anyone.</i>&quot;<p>You sure about that? I know quite a few people who are seemingly only interested in science fiction and gaming it its various forms and <i>aggressively</i> disinterested in anything else. Maybe you know some, too: people who use terms like &quot;sports ball&quot; and whatever the current incarnation of &quot;mundane&quot; (as a noun) or &quot;muggle&quot; is. Believe me, it&#x27;s no more appealing than hanging with a group of, say, serious football fans (for the appropriate value of &quot;football&quot;).<p>I don&#x27;t feel the need to demonize anyone, but decent people doing what they feel are innocent things can successfully masquerade as a conspiracy for as long as you care to watch.
