正方辩词：
Everyone has the right to express himself online.
每个人都有权利在网上发表言论。

I think the Internet provides us with a free space to express our own opinions. Everyone has the right to express himself online no matter what he says. For different people may have different ideas towards the same object, you should not judge other's opinions based on your own. At present, some people like to attack others' opinions on the forum. In my mind, you can reject others' opinions, but you can not regard them wrong.
我认为网络给所有人提供了一个自由发表言论的平台。人人都可以在网络上畅所欲言。然而，对同一事物的看法往往因人而异，所以我们不应该只站在自己的立场上看问题。现在，有许多人喜欢在论坛上攻击别人的观点，但是依我看来，你可以拒绝接受他人的看法，却不能说别人的看法是错误的。

反方辩词：

One should be responsible for what he says
每个人都要对自己说的话负责任。

Nowadays, more and more people tend to express their own opinions on the Internet, especially in the forum. But I think, we should be responsible for what we say. If an opinion is wrong, it should be criticized by the public. Although everyone has the right to voice himself, he should be clear what he can say and what he can not. If his opinions are against the law or the basic moral, he should be criticized by people.
如今越来越多的人愿意在网上，尤其是在论坛上，发表自己的观点和看法。但是我认为每个人都要对自己说的话负责任。如果观点是错误的，理应受到公众的批判。虽然每个人都有权利发表自己的看法，但是我认为他应该清楚什么话该说，什么话不该说。如果所发表的观点是违背法律或者道德的，他理应受到公众的批判。
