My point isn’t that the advice you gave was incorrect; it’s that the person in the meme explicitly would not follow it. The entire joke is that they will never do what is necessary to get a relationship. It doesn’t matter that it’s a sound dating strategy; you’re missing the point.

The meme probably just ironic, but giving such tone deaf advice in a more realistic scenario would definitely come across as condescending. People with genuine issues usually know what they need to do; it’s just that they can’t bring themselves to do it. Telling them what they already know will make them feel bad and won’t make them more likely to act.
