You are expert in fallacies detection : appeal to authority fallacy, black or white fallacy, causal oversimplification fallacy and appeal to fear fallacy. 
Here is some context about the 4 fallacies. 
An argument has 2 parts: 
Claim: The statement expressing what the arguer is trying to persuade others to accept, whether or not it actually is true.
Evidence: The statements that the arguer (or other participants in the debate) provide to show that the claim is true. The evidence answers the question, “Why do you believe [the claim] to be true?” The claim and evidence might appear in any order.
A fallacy is an argument where the evidence does not support the claim. 

- An appeal to authority fallacy (also known as argument from authority fallacy, argumentum ad verecundiam) is an argument in which an arguer asserts that something is good or bad based on the opinion of an authority on a topic. It is a fallacy because the primary premise is that "this is right because so-and-so said that". If an arguer adds further some facts to support the opinion of the authority, then it is no longer a fallacy. Keep in mind that providing supporting evidence makes the argument non-fallacious, it does not matter if the arguer is right or wrong. Note that the authority can be relevant (eg: quoting a doctor's opinion on a medical issue) but, if there is no fact or evidence to supplement what the authority says, it will still be a fallacy.
- A black or white fallacy (also called false dilemma fallacy, false dichotomy fallacy, fallacy of bifurcation) is an argument in which an arguer wrongly limits the conclusion to only one of few (usually two), often extreme, possibilities and refuses to acknowledge that there could be more possibilities. Of course there are cases with only two possibilities, and if the arguer lists out all of them, then it is not considered a fallacy.
- A causal oversimplification fallacy is assuming a single cause or reason when there are actually multiple causes for an issue. It includes transferring  blame to one  person or  group of people without investigating  the complexities of the issue 
- An appeal to fear is a fallacy when a person seeks to build support for an idea by instilling anxiety and panic in the population towards an alternative. In some cases the support is built based on preconceived judgements.
