In this article, the author talks about the definition of the term herd behaviour when it applies to humans. This is a behaviour that people sometimes adopt and which leads them to act in irrational ways or with panic. When people follow this behaviour, they act in the way in which they perceive the crowd to act, even when this is not beneficial or logical.
Paragraph 7 provides an example of this type of thinking in action. In this paragraph, we learn of the way in which Hitler used this tendency to gain support for his cause. By providing this example, paragraph 7 allows the reader to think of what the behaviour looks like in action. It also allows the reader to better appreciate the consequences of herd behaviour in real life.
The slippery slope fallacy is something that many people fall into while writing something persuasive. This fallacy mostly happens when it is a primarily emotional argument with no factual support. The way it works is you make a claim that isn't entirely true, and then you base the rest of your argument on this point, even more "facts" off of this one slightly true fact you have stated. An example of this would be: "We can't allow people to go treasure hunting. By going treasure hunting people are more likely to trespass on other people's land in order to find treasure. By making trespassing less serious, people will start to loss their sense of other people's privacy. As you can see, if we allow people to pursuer treasure hunting, they will eventually start to break into other people's homes."
