You know they are here, people commit logical fallacies all the time, so just that we are clear I will list the most common ones for fun, in the order I have seen them being posted.
Straw man to create the illusion of having refuted a proposition by replacing it with a superficially similar yet unequivalent proposition (the "straw man"), and refuting it, without ever having actually refuted the original position.
Ad hominem attacking the arguer instead of the argument.
Argument from ignorance (appeal to ignorance, argumentum ad ignorantiam) assuming that a claim is true (or false) because it has not been proven false (true) or cannot be proven false (true).
Onus probandi from Latin "onus probandi incumbit ei qui dicit, non ei qui negat" the burden of proof is on the person who makes the claim, not on the person who denies (or questions the claim). It is a particular case of the "argumentum ad ignorantiam" fallacy, here the burden is shifted on the person defending against the assertion.
Red herring a speaker attempts to distract an audience by deviating from the topic at hand by introducing a separate argument which the speaker believes will be easier to speak to.
Equivocation the misleading use of a term with more than one meaning (by glossing over which meaning is intended at a particular time).
Argumentum ad populum (appeal to belief, appeal to the majority, appeal to the people) where a proposition is claimed to be true or good solely because many people believe it to be so.
Argument from silence (argumentum e silentio) where the conclusion is based on the absence of evidence, rather than the existence of evidence.
Argument from fallacy assumes that if an argument for some conclusion is fallacious, then the conclusion itself is false.
