Is 'go easy on me ' correct?

I find I have been in error. I am correcting before the Grammar Police arrive "To serve and Correct".

The sentence is an Imperative and as such the subject, You, is implied. The speaker is not the subject here. The one spoken to is the subject.

As pointed out in thoughtco.com Imperative sentences may seem to have no subject, but the implied subject is you, or, as it is properly called, "you understood".

To go easy means to use less than the standard or usual amount of force of whatever kind against the "victim". This can be used in many ways. If I, the young man, am subject to the amorous assault of a beautiful woman I might ask her to "Go easy on me" if I, unaccountably, wished her not to succeed in her efforts. Ain't fiction grand?
