I would agree with you there, although I don’t believe idol is the correct term. They have become acceptable versus taboo, but I think it all does tend to head back to hedonism.
Many people want to live life according to their pleasures, a supposed care-free life in which they are in complete control. But such an ideal is never possible because once we achieve receiving all of the pleasures we wish for, free of all oppression or complications or consequences and it is all under our control, we’ll wish for something else, something that we see as better. Such a lifestyle will never be attainable because once we fill ourselves with all of those worldly things, we’ll still feel like something’s missing.
The road to hedonism leads to a never-ending cycle of seeking pleasure, attaining it, and then seeking pleasure again. One can never be satisfied.
And that seems to be the culture we are in currently. People want abortion to be acceptable because that means they can rid themselves of the consequences (the possibility of having a child) while still attaining the pleasure they seek (sex). People want same-sex marriage to be acceptable because that means they are not outside of natural law because gay marriage is “natural.” It is easier to pretend to be normal or pretend something is acceptable than to face the truth of our sins. We prefer to explain away our sins (abortion is okay because they are not really alive anyway or gay marriage is okay because it’s only fair that everyone should be allowed to love anyone they want) than to face the truth that we are wrong. It’s so easy to get caught up in the pleasure of the moment than to face the bitter truth.
