Heavy Anti-Trumper here, Hi.
I would like to cordially disagree, as when Trump was doing all of his Ukraine Shenanigans, I held the flag upside down as when I researched it, I found that it means "SOS" (or something like that.
I figured our country was being held hostage by a madman. So, until our country was rid of the orangutan, my twitter image was the inverted flag. It was a call out to our allies saying "Hey, I don't like what he's doing, I think he's deplorable and not representing what Americans really are." with an image.
