Yup... the logic displayed in this meme's main argument is on par with the dreck pumped out by the media; half-truth, misrepresentation, omission.
Note how the meme was framed. Nothing was TECHNICALLY incorrect and you can't blame anyone for asking a dumb question but the inference is that we are not only a monarchy but one built on religious supremacy. It's always interesting to see this in the wild... an incomplete argument being conveyed though the use of an erroneous supposition in question format.
And then we wonder why the rest of the world view us as a bunch of idiots.
