Today's motion is: 'Social media does more harm than good.' The affirmative team will speak first.
今天的辩题是：'社交媒体弊大于利。'正方先发言。
Affirmative
We argue that social media harms mental health, spreads misinformation, and creates addiction. Studies show that teens who use social media more than 3 hours daily have double the risk of depression.
我们认为社交媒体损害心理健康、传播虚假信息、制造成瘾。研究表明每天使用社交媒体超过3小时的青少年抑郁风险翻倍。
You (Negative)
We contend that social media's benefits outweigh its risks. It connects people across borders, enables social movements, and provides access to education for billions. The affirmative's argument assumes users can't exercise self-regulation, which is an oversimplification.
我们认为社交媒体的益处超过风险。它连接跨国界的人、推动社会运动、为数十亿人提供教育机会。正方的论点假设用户不能自我调节，这是一种过度简化。
Affirmative
But self-regulation has proven insufficient — that's exactly why regulation is needed.
但自我调节已被证明不够——这正是需要监管的原因。
You (Negative)
That's a red herring. We're debating whether social media is harmful, not whether it should be regulated. Even with regulation, the fundamental benefits remain.
这是偷换概念。我们辩论的是社交媒体是否有害，不是是否应该监管。即使有监管，根本的益处仍在。
