<p>Cicero said:
</p>
<p>Some opinions are better than others.</p>
<p>If you tell me that you want to kill ten percent of the people in a country, I’ll listen to you politely and then, if you seem to be serious, I’ll have you institutionalized.</p>
<p>Opposing gay marriage is much less egregious—rather than kill them, you just want to legally denigrate ten percent of the people in a country for no good reason. So I won’t call the cops, and I might even end up being friends with you. But you should expect that it’ll worsen my first impression of you.</p>
<p>(Note: dunno if the proportion of gays in society is actually ten percent.)</p>
