When I first heard from about the concept of Logical Fallacies, I thought it was a little strange since the only real fallacy you can actually commit in logic is a circular prove. Generally 99% of all arguments in the real world should not be classified as logic arguments. A logic argument is defined rather simple: if your preconditions are true, your conclusion has to be true based on the structure of your argument.
An appeal to authority however can be logical. If you take a statement by a biology professor as a fprecondition in the context of an argument about logic, that is perfectly fine. Hell, in the realm of logic you could even have the precondition: "Everything that Person X says is true". As long as everybody involved in the argument can agree on this precondition, the logic of the argumentation is not harmed. To be fair many people dislike precondtions that determine the truth of a statement depending on a source, but it is quite common especially in science.
Appeal to emotion is OK, because emotions are more important to facts.
Whataboutism is what actually made me look deeper into the topic of logical fallacies. Someone on youtube mentioned that my logic was flawed, because I was talking about the hypocrisis of the left. Ofc the word on its own signaled that it is a rather new american concept. No actual modern pilosopher would ever create a erm as childish as this.
If someone is criticing you and your counter argument is "you are doing the same", then that is perfectly fine. In fact I think logic is a great tool to detect hypocrisy and to call the act of pointing out hypocrisy "whataboutism" is beyond stupid. It is propaganda developed during the cold war to not face the legitimate claims of the Sovjet Union about the hypocrisy of American Politics.
To people wo think logic is directly connected or even defined by this bs about logical fallacies: study logic or math, and then try again. If you don't want to invest that amount of money and time then feel free to ask me about logic in the comments. I tutored the subject for a year at college.
Edit: Changed the title to something more snappy, this word really triggers me :3
