What was laughably wrong is that you seized upon the end of the little ice age as the point-in-time from which you claimed the planet's glaciers started retreating.

It is irrelevant whether the little ice age ended 456 years ago, 500 years ago, or 15 minutes ago. It has nothing to do with the point when retreat began.

Which, BTW, was thousands of years before that.

Which you will no doubt seize upon as validating your preconceived notion of what is happening. Alas that date too is irrelevant to current climatology.
