I'm sure many supporters of Brendan Eich's ouster are completely sincere, but it's difficult to explain the <i>intensity</i> of their feelings on this issue. It can't be as simple as "civil rights" and "marriage equality"; for example, (first) cousin marriage is important to many groups—indeed, in Islam cousin marriage is not only allowed, it's often preferred [1]—but it is illegal in most states [2]. And yet, I rarely see advocates of "marriage equality" get all lathered up over this issue. Are advocates of "marriage equality" in favor of legalizing cousin marriage? If not, why not? If so, why have they not worked harder to achieve it?<p>I see no way to resolve this paradox from within the context of progressive ideology, but it's trivial to explain once you view it from the outside. As the example of cousin marriage shows, the behavior of Eich's purgers <i>is not</i> consistent with mere "civil rights" and "marriage equality", but it <i>is</i> consistent with signaling tribal membership, seizing political power, and smashing their enemies.<p>As it happens, right now gay marriage is an effective club with which progressives can beat conservatives. At some point, this may also be the case for cousin marriage—I can easily imagine opponents of cousin marriage someday being branded "Islamophobes", just as today opponents of gay marriage are branded "homophobes". But I predict that this will happen if, <i>and only if</i>, it serves progressive political ends.<p>[1]: <a href="http://wikiislam.net/wiki/Cousin_Marriage_in_Islam" rel="nofollow">http://wikiislam.net/wiki/Cousin_Marriage_in_Islam</a><p>[2]: <a href="http://en.wikipedia.org/wiki/Cousin_marriage_law_in_the_United_States_by_state" rel="nofollow">http://en.wikipedia.org/wiki/Cousin_marriage_law_in_the_Unit...</a>
