Why should I be aware of everybody's likes and dislikes?

Because empathy towards your fellow human beings is a virtue and not giving two flying fucks about anyone except number one is not very nice. You may choose to live your life that way, but plenty of people in the world actually care about people aside from themselves.

Are we going to call meat "animal-sourced food" next?
