I generally believe everyone is intelligent in their own way. However, there are some things that people say that make them look stupid. For example...
1. It's so cold outside. Global warming isn't true. Some people say it as a joke. Other people actually believe it.
2. Nothing can change my mind. Really? Information and facts won't change your mind? Even an atheist must concede that there is a God if God showed up.
3. Well, that's my opinion. This is fine if you are just stating your opinion. If you don't like gays, then fine. However, that doesn't make any sense why you would want to take away their rights. I don't like people who eat on the subway. That doesn't mean they shouldn't be allowed to marry.
4. You have to give respect to get respect... People who say this while they are disrespecting others totally miss the point.
5. The Bible is true because of this story from the Bible. I have nothing against Christianity, but this makes no sense. This argument is the equivalent of "Cause I said so."
More as they come....
