I don't think it's particularly useful to compare the GB and the Democrats.
Believe me, I don't really like the Democrats, and if I lived in America I'd probably vote Republican. But politics in the West is not a cult, however cult-like political extremists can be.
You can vote Democrat, then if you find out stuff about them that's not cool, you can vote independent or Republican.
Political extremists of any stripe have cult-like tendencies but the GB are actual cult leaders.
If the GB ruled an actual country, that country wouldn't look like the US, it would be more like Saudi Arabia, lol.
