I think it's all of the above.  I'll add that parents aren't raising their children with a good foundation of right and wrong, morality, consequences and instilling integrity.  Kids are lost these days without good mentors.  The youth puts so much emphasis on sports, entertainment and influencers rather then looking at the real hero's such as caring people in their community, those people in the sciences and people willing to make a difference by standing up for what is right rather then caving, hiding and not owning up to their mistakes. 

Your post on X is interesting how it migrated in answers.  People sit behind a computer screen and feel empowered at their keyboards which can make them bullies, and not focused on the question at hand.  I get so annoyed at some of the comment threads on some news articles I read that they stray so far from commenting on the article content that the whole comment thread is worthless dribble of accusations as opposed to thoughtful comments. 

Politics has been a real divider in the US, so much so that family and friends have cut each other off because of their beliefs rather then accepting their differences and trying to get along. They choose to not get along because that's much easier.  The hard part is sitting down with someone and having the conversation and working out differences without the name calling and the heated conversation that usually doesn't end well.  Someone is going to leave the table sad and defeated without accomplishing anything and the other person will gleefully feel more empowered because they remained the ultimate jerk and they think that's right.  Makes me crazy.  I see it all of the time online with people having political mayhem and it's ugly.
