Also, nice to see you're still talking straight out of your ass, Massively. Anyone who actually lives in the real world knows moral relativism is a juvenile, self-refuting fantasy entertained only by emotional and social cripples unable to reconcile themselves with reality.
Take a good look at cases of Borderline Personality Disorder.
And yes, moral relativism is much more... realistic than absolutism and universalism. A primary criticism of Moral Absolutism regards how we come to know what the absolute morals are. For morals to be truly absolute, they would have to have a universally unquestioned source, interpretation and authority, which is an impossibility.
Another of the more obvious criticisms is the sheer diversity of moral opinions which exists between societies (and even within societies) in the world today, which suggests that there cannot be a single true morality.
You could try and say that in its purest form, moral relativism is an example of a self-refuting idea; the principle that "all moral frameworks are relative" being, itself, an absolute moral framework. In practice, though, it tends to be "All moral frameworks except mine are relative" which is instead an example of special pleading. Which is what I'd label yours as, since you seem intent to decry any morality that isn't based on your own.
The above critique, however common, is rather weak as moral relativism should not be classified as a "moral framework" as it does not prescribe any moral values or principles. Moral relativism in its purest form is the observation that all moral frameworks share a common trait - that they are not absolute. Therefor, there is no moral absolute. No moral objective. There is no such thing as 'inherently wrong'. If there was, it could not exist.
It also takes the form of defining evil.
Sociologically speaking, it is the limit of "I/we don't like that." It is the opposite of "good" in the moral spectrum and is simply defined by Merriam-Webster as "morally reprehensible." To endure some suffering is a sign that evil is about. The definition of an activity as evil varies with time, place and circumstance. Which of course leads back to relativism.
