A very intelligent person can have some very stupid ideas. The fact that they are intelligent does not make their ideas intelligent as well. Referring to an idea as stupid is not the same as referring to the progenitor as stupid.
You do not understand how logical fallacies work. This is demonstrated by your responses.
Furthermore, saying the equivalent of x person is smart therefore they are right and as a result I am right because I invoked person x is an appeal to authority.
Ding ding, ok school is in session:
Ad hominem attack defined
An ad hominem attack is when someone tries to win an argument by attacking the other person's character instead of addressing the actual issue or argument. It's like saying, "You're wrong because you're a bad person," instead of explaining why their idea might be incorrect.
Example
If you call an idea "stupid" but focus on explaining why the idea itself is flawed, it’s not an ad hominem attack. For example:
Not an ad hominem attack:
"The plan to build a bridge out of paper is stupid because paper isn’t strong enough to support any weight."
In this case, you're calling the idea "stupid" but you’re explaining why it’s a bad idea based on its merits.
Ad hominem attack:
"You think we should build a bridge out of paper? You must be an idiot."
Here, you're attacking the person rather than addressing the reasoning behind their idea.
This endeth the lesson.
