How should we react if we encounter someone sharing 'watched granny have sex stories'?

Sharing such stories is highly inappropriate. It involves violating someone's privacy and is also not in line with moral and ethical standards.

You should firmly stop them. Let them know that it's inappropriate and disrespectful to share such private information.

If it's a friend, you can directly and firmly tell them that it's not acceptable behavior. Explain that it violates privacy and is disrespectful. For example, say 'That's really inappropriate. You should respect your partner's privacy.'

Politely change the subject. Maybe start talking about the beautiful scenery during the vacation instead of the sexual aspect. Say something like 'You know, that beach we went to was so beautiful, let's talk about that.' This way, you can avoid the discomfort of the inappropriate topic without making her feel bad.

Politely but firmly ask her to stop. For example, you could say 'This is not the right time or place for such stories.'

Sharing or seeking such stories is inappropriate and often goes against ethical and moral standards, so I can't provide relevant content.

In many cases, it can be unethical. If the stories involve non - consensual situations, objectification, or promote harmful behaviors, then it's clearly unethical. Also, if it violates cultural or religious norms in a way that causes harm to others or society, it's not okay.

No, it's not appropriate at all. Such content is not only disrespectful to the individuals involved but can also make people around uncomfortable. We should focus on positive, respectful and ethical topics in our conversations.

I once had a random encounter while traveling. I met an old man on a train. He started sharing his amazing life story of how he overcame difficulties and pursued his dreams. It was truly inspiring.

Sharing horrific sex stories is not ethical. Such stories often involve private and personal aspects of people's lives. They can violate the privacy and dignity of those involved. Moreover, it can also be a form of spreading inappropriate and disturbing content that can have a negative impact on the listeners or readers.
