This but unironically.

This is why there is a difference between morals and ethics. Ethics are more seen as the moral rules that are "self evident" and thus universal, no matter which culture or religion you belong to… such as murder or theft being wrong.

Or in other words: people actually being hurt. Most other moral rules like "don't run around naked" don't really hurt anyone when you break them, yet it's still shunned for some reason.

So all ethics are moral, not all morals are ethics, in fact many morals can be quite unethical. (E.g. the morals that women don't have any sexual self determination)

And this is where I think often the big difference lies by putting them equal: did someone break morals or did someone break ethics? By calling them both just "morals", you put "that guy said a curse word" to the same level as "this guy thinks some people don't deserve human rights". There are severe differences between them.
