I see no text on the page you linked that references any connotation of superiority or purity. The first usage of the meme does not suggest either a superiority or a purity, as you claim; however, an audience might project their preferences and gatekeeping onto that which is without bias. In the vast majority of the examples in the link, there is simply a contextual miscommunication between two valid interpretations of a term; only a few examples do suggest superiority or purity. Deferring to imgflip, many of the user-made memes do not have that connotation, while some do. Based on these data, I do not see a subtext of connotation or purity to be necessarily implied in use of that template. The comedy can be derived from something as simple as a word having two meanings.

Once again, you have also claimed that I said something which I had not (prior to this comment).
