It is a message that there is no smoke without fire. The "intellectual" (note the glasses) has a seemingly convincing argument, but is shown to be a fool. The suspicion of sinful, non-procreational sex (notice the falling leaves, which do not play a reproductive role in trees) turns out to be true.
This belief in smoke without fire feeds into the conservative tenets of anti-intellectualism, the tendency to assume guilt based on prejudice and fuels paranoid conspiracy theories. It is also a meta-dog whistle confirming that yes, those other dog whistles the comic uses are really what you think and not just coincidental.
Remember: on the internet, nobody can hear your tone of voice. If you want your dry jokes to land, you'll likely need to use "/s" to show that you were being sarcastic, otherwise people might think you're being serious about such an obviously absurd, irrational stance, because there really are people who would believe the things you joked about.
you may have heard the phrase "god works in mysterious ways". This is clearly one case of such. Clouds do not normally behave like this, it's closer to what you might think of smoke. And where do we see white smoke? That's right. When the Papal conclave has come to a decision for the new Pope.
These are hilarious lmao. You're insane if you think the punchline of "the stick figure falls and his body spells 'OK' after the other guy says 'you'll be ok'" is pandering to hypochondriacs, btw.
I guess it's the point of sarcasm really, that not everyone will get it right away. I hate when people feel the need to do the "/s" though, it completely defeats the point.
