Looking for examples of the slippery slope fallacy

Hey All,

I'm making a resource for high school students to learn about the slippery slope fallacy and I'm looking for some real-life examples to use such as interviews, online articles or videos. Since I'm trying to make it broadly accessible, I'd like to steer clear of potentially loaded topics such as marriage equality, voluntary euthanasia, abortion etc. I'm looking for things more along the lines of increased taxes => communism, or, legalising cannabis => all drugs become legal => society breaks down. Something along those lines. Any help would be very much appreciated!

When doing this exercise, don't fall into the Fallacy of the False Alternative. For example, increased taxes => communism.

In addition to communism, increased taxes could result in one or more of the following: decreased overall production, growth of the underground economy, totalitarian government, decreased revenue for the government, and so on. 

Perhaps you could have the students think about all the consequences of increased taxation. The same with the other subjects to make them less limiting and encourage the students to "stretch" their minds. 

One famous example is, "if you legalise gay marriage, soon they'll let people marry animals!"
