To what extent are moral ideas reflect society around us, and to what extent are we free to think for ourselves about moral matters?

Moral ideas reflect society through collective behaviors that are presented by a large part of the population. These behaviors determine how far we are free to think about moral issues, as there is a social pressure that we associate our thoughts within this collective behavior.

Explanation:

Moral ideas determine what is right and wrong within society. This makes the population organize to act and behave in accordance with these oral ideas, collectively, always encouraging what is considered correct, good and progressive. This type of concept limits the freedom of individuals to think for themselves and reach their own conclusions about moral issues and social behavior, because there is pressure for the moral ideas accepted by most members of the population to be accepted without debate. For this reason, issues such as homosexuality, abortion, euthanasia, among others, are sources of criticism for a social minority, which decides to take a stand on these issues in a way contrary to the positing revealed as a moral idea by the majority of society.
