FALLACY OF COMPOSITION (PART TO WHOLE)
If true about on part of X then true about all parts of X

FALLACY OF THE SLIPPERY SLOPE
“If we paint Christmas trees purple, then there will be less green Christmas trees.
If there are less green Christmas trees, we will diminish the Christmas spirit.
Diminishing the Christmas spirit will lead to fewer sales at Christmas.
Fewer sales at Christmas means less tax money collected.
By decreasing taxes, government revenue is diminished! Diminishing government revenue will force our national defense to be
cut!
Cutting national defense will lead to a decline in our military power!
A decline in military power will lead to the United States resigning as the world’s superpower!
The elimination of a superpower will lead to international instability! Instability will lead to nuclear war.
Nuclear war will create a world-wide Armageddon!!
And a world-wide Armageddon will lead to the end of the world as we know it!!!” ~ Kathleen Knudsen

STRAW MAN
Setting up a false argument and attacking it.
Professor Windell does not want to invest federal tax dollars into the solar energy project. I simply cannot understand why he wants to turn our country into a desert wasteland. Any professor who wants to do that is not qualified to teach and thus should not be able to teach.
