What are you talking about? Common sense is literally a cultural POV, I mean it has the word COMMON in it, and therefore by definition dependent on that common thread of culture or human knowledge; it is a relative term that's developed through a common experience, which is transformed into a sense, but it's an acquired sense nonetheless.
As for morals, we are animals, and animalistic, thinking otherwise, or towards some fabricated ideal, is untruthful, and therefore amoral.
However for the functioning of a society it is necessary to establish both, morality, and inevitably common sense, and your adverse reaction to such other moralities, or POVs is a direct result of societal conditioning, which is good, because it creates stability in this society.
