"the objective morality we all have comes from the Lord"
Those who are naturally beneficent rather than malignant have no need of threats of eternal punishment meted out by a deity in order to be "good" people -which is wholly the point of the meme.
"a persons refusal to accept that and instead fall down the slope of subjectivity is the corruption via your free will. And yes, without free will people can literally become hitler and you don't have an objective argument against it."
Contradictive statements; free will is what allows people to choose between Hitler/non-Hitler paths, benevolence/malevolence, the choice to "become Hitler" is subjective -ergo, those two sentences cancel each other out, equate to a zero sum.
"Aztecs sacrificed their children, Hindus burned widows alive, muslims honor killed their daughters.... and in a subjective setting the only real response is along the lines of
'i dont agree with that in particular so how about you just abort babies and tell your kids they need hormone blockers like we do instead'."
You opened by asserting that "the objective morality we all have comes from the Lord" but now seem to be arguing that morality is subjective, untethered to deific mores. The cited Aztecs, Hindus, Muslims all acted in concordance with the "objective morality" coming from their respective Lords. Moreover, attempting to conflate ritual murder ordered by a deity with elective transitional medical care is disingenuous.
"I understand you purposely had to misunderstand the point of the argument to make this meme but just thought id point it out incase anyone was dumb enough to think this is actually a response to something."
Although a tad dramatic, the meme makes a straight-forward, stand-alone, logical statement regarding the nature of human quality of character, points out that "good" people don't have to be under threat to ensure they continue being "good". Again, self-contradictive statement: you assert the meme is in response to an argument only to turn right around and assert that the meme is not in response to an argument.
