I like it, because it's likely to also be in reference to minding one's own business, as in not butting your nose in where it doesn't belong. Cable news as we know it might die within a month if we all starting doing that.
I don't know where you get the idea that this is an issue of "Trump supporters." To things like this and the offense taken over the NFL players taking a knee, you are blinding yourself to the fact many people who aren't Trump supporters believe "in god we trust" and "one nation under god" should stay, and would be very offended if they were removed. They've been around way longer than Trump's political career. Rather, they tend to be "god and country" types, and sometimes they even vote Democrat, and even with a good number of them having voted for Hillary.
There's really no reason to assume such issues are exclusive to Trump supporters, and that Trump supporters hold similar positions on the subject. With the kneeling and "under god," it's more of a Conservative thing than a Trump supporter thing. Even if Hillary was in office, their would still be people outraged over such things.
