I don't really want random people fucking in the streets, that's not even about the taboo aspect of it. Get a room.

That's exactly the taboo aspect of it.

Replace word “fucking” with any other activity and you’ll see how taboo it is. Hint, try “laughing”, “hugging”, “playing”

A softer facet is kissing in public, or PDA's how they're called by some. I find it ridiculous some people are offended by this, but maybe I am extremely shameless.
