It is fascinating how low one's scores can drop for taking sides in the realm of politics, but I can't be authentic with this universe of mine without having Ian assert his divine will in a benevolent manner. Some might think me (or him) a hypocrite, but if you'll notice he largely left his critics and detractors alone for two months.
When it was just directed at him, even when it might be used to foment insurrection against him by the churches (to their own self-destruction, but not by means that he wished to use), he was prepared to have her offed quietly. When she began potentially causing pogrom against Jews in North America and elsewhere, though, he had to step in there. He didn't want to censor or cause others to self-censor dissent on general principles, but he had no more patience with the kind of irresponsible talk that had caused widespread persecution against his own people for centuries.
Since the First Amendment protects free speech against the US Government (and by incorporation under the 14th Amendment, the States and communities), it doesn't come into play here. This isn't government censorship. It's the wrath of a Deity, divine justice and judgment against a voice of hate and malice. Even her horrid afterlife isn't eternal, so he's much more magnanimous than the Christ that she worshiped. It's perhaps a bit intolerant of him, but he's been very patient and gave her the show to mend her ways first, and he only acted the way that he did because he could anticipate the outcome and wanted to prevent: a religious war and attempted genocide.
