It absolutely did not amount to one single, giant leap all of a sudden.
The same goes for pretty much any other example you can think of. Pick an issue, and I'll point out how there were a multitude of prior, earlier steps towards that goal, either legislative or cultural or both (as legislative attitudes reflect culture, largely, they can't be considered separately).
Some of those small steps can be so momentous in the moment that they'll trigger passions so hard they cause riots and even civil wars, but it doesn't make them something other than the incremental step that they were.
The entire point of incrementalism as a viewpoint is that you look for the long-term goals, and determine if you're moving closer or further away, and as long as the answer is "closer", you're okay with that, or even if you manage to hold steady against a strong regressive movement trying to set you back. The alternative, which is becoming far too common, is to pick some arbitrary short-term goalpost, ignore the long-term view, and then demand to achieve that short-term goalpost in full right now or shit's fucked RIOT. Take the push for M4A, if you want an example; they generally lose sight of the long-term goal (making sure everyone's health is protected) in favor of one specific step forward on that issue, rejecting any different steps because they're not this step. Even if they're steps on paths leading to that same long-term goal.
