I dislike the format of posts of "If you believe/assert X, you're telling on yourself", followed by an explanation of why X implies Y, with Y either stated or impled to be bad. It feels presumptuous and patronizing in a way that just saying X is wrong because of Y wouldn't. The phrasing implies a there's consensus against Y with some authority, but the implication from X to Y is generally either clear enough that the people asserting X will probably be aware of it already, or itself debatable. Since there are people with that opinion, there's not a consensus, or if there is then the X-believers are already going against the consensus anyway, and don't respect it enough that the "telling on yourself" thing makes sense. It feels like the people making these posts are trying to claim authority from nowhere.

(I do have a specific example in mind, if you were wondering, but it's not actually a social media post. It's an excerpt from Martin Luther's theology book On the Bondage of the Will.

Therefore come forward, you and all the Sophists together, and produce any one mystery which is still abstruse in the Scriptures. But, if many things still remain abstruse to many, this does not arise from obscurity in the Scriptures, but from their own blindness or want of understanding, who do not go the way to see the all-perfect clearness of the truth. As Paul saith concerning the Jews, 2 Cor. iii. "The veil still remains upon their heart." And again, "If our gospel be hid it is hid to them that are lost, whose heart the god of this world hath blinded." (2 Cor. iv. 3-4.) With the same rashness any one may cover his own eyes, or go from the light into the dark and hide himself, and then blame the day and the sun for being obscure. Let, therefore, wretched men cease to impute, with blasphemous perverseness, the darkness and obscurity of their own heart to the all-clear Scriptures of God.

Of course, Luther doesn't phrase it in the same way as modern Tumblr-users. Also, in this case he does actually cite an external authority, so this is more an example of doing it right than the thing I'm complaining about. The connection only came to mind because when I first saw this passage, the Bible quotes were omitted.)
