9. Slippery Slope.

The Slippery Slope fallacy is committed when the conclusion of an argument depends on an unlikely chain reaction stemming from the conclusion. J. Matt Barber uses this fallacy in a recent news article. The argument starts with accepting the 'Day of Silence', a day in which students remain silent all day to protest the actual silencing of LGBT people due to harassment, bias and abuse in schools. The argument states that the homosexual lifestyle is dangerous, and if we have a day to promote it, then we should promote other dangerous lifestyles, such as doing drugs.

"Can you imagine officials at a middle school, junior high or high school setting aside a day to promote "tolerance" for heavy smoking and drinking among children? How about a day where teachers encourage kids to "embrace who they are," pick up that crack pipe and give it a stiff toke?"
