The problem with your selection is that it's interpreted as the most outlandishly fringe extreme religious/conservative viewpoint, and thus it has a political angle. I would have gone with something like the government being run by lizardmen aliens (which some people in the world claim to believe).

> I tried to pick an example that is both held by people in the world today, thus it couldn't be easily dismissed as unrealistic

It is very easy to dismiss a "death to homosexuals" discussion among Google employees as unrealistic.

Hrm, I understand that logic, but it seems like an attempt to frame disagreement with the current popular political view in the most extreme way.

Maybe that's not what you intended, but since that is a commonly employed technique ("everyone who doesn't disagree with me is a nazi") it does seem that way.
