In a recent episode of the Colbert Report, Stephen Colbert tackles the issue of Obama's immigration speech. Along with FOX News he calls the order executive amnesty. He claims the executive amnesty gives the immigrants more rights than just citizens. He also mentions early immigrants, but claims that they were different. He then goes on the compare Obama to an emperor. He also says that riots may occur from people seeing how same things are. He uses a slippery slope fallacy here. He also claims that Obama is declaring war on the constitution, which is a faulty analogy.
Colbert is jumping to conclusions without, as he admits, even hearing the speech. He accuses Obama of overreaching his powers, and tries to discredit him. He is emulating the conservative media and their attacks on him. Colbert does not follow logic in his stories so much as heart and his own word, truthiness.
