What is the difference between a Straussian meme and a double entendre?

Allegedly a Straussian meme is "self stabilizing" because it imposes some sort of cost to buying into the lower or higher meaning. So it's a multiple entendre that has ideological or epistemic implications. (I'm not convinced this is a thing, the examples were pretty contrived.)

Whereas in the example here, acting on that advice is costly (it means losing friends) but believing it is free. And there aren't different layers of meaning accessible to different parties. It's straightforwardly a play on words.

I think one is more interpretation vs lexical similarity
