1. Current events: Discussing current events is a great way to start a group discussion as it provides a platform to share opinions and perspectives on topics that are relevant and impactful. Some examples of current events that could be discussed include political news, social issues, and global crises.

2. Personal experiences: Sharing personal experiences is a great way to create a sense of empathy and understanding within a group. This could include sharing stories about overcoming challenges, memorable moments, or life lessons learned.

3. Pop culture: Pop culture is always a popular topic for group discussions as it is something that most people can relate to. This could include discussing the latest movies, TV shows, or music.

4. Controversial topics: Controversial topics can be a great way to spark heated debates and discussions within a group. However, it is important to approach these topics with sensitivity and respect for differing opinions. Examples of controversial topics include gun control, abortion, and climate change.

5. Hobbies and interests: Discussing hobbies and interests is a great way to get to know each other on a personal level. This could include discussing favorite books, sports, or travel destinations.
