CMV: "No parent is perfect" is an empty statement that does not justify or excuse your failings as a parent.

There are many communities here on reddit that relate to parenting concerns; ranging from children criticising their parents methods and parents raising concerns about their own parenting.

A common statement brought up by users as a form of reassurance or rebuttal is "no parent is perfect".

Now this statement is absolutely true. No human being has ever achieved "perfection" in parenting. Even overall amazing parents had their flaws - and thus were not perfect. The concept of a perfect parent is mythical.

This is where the issue lies; saying that "no parent is perfect" is basically telling us nothing about that individuals performance as a parent - it's basically just saying; "I performed under impossibly perfect, which is anything from scumbag to hero".

This kind of rhetoric is empty and useless and should not be used as a form of reassurance to parental failings or criticism to complaints towards parents. Everything should be judged on it's individual merit in this context.

The phrase is not used to justify or excuse incorrect action by a parent. The parent is still responsible for the child and should learn from their mistakes. 

The phrase is used to comfort a parent that already knows a mistake/failure occurred and feels overly down about themselves as a parent.
