argumentum ad populum (Latin: "appeal to the people"), in logic, is a fallacious argument that concludes a proposition to be true because many or all people believe it; it alleges that "If many believe so, it is so."
Your opinion no matter how numerous don't mean your right , its weak logic.
It's not my opinion alone. It's the majority of people on bodybuilding websites that crushes your whole argument.
No, by your logic, for example:
"People vote for a President. The person with the most votes wins and becomes President and the people with the least votes lose right?" Using your logic, the person with the most votes does not win and should not be president.
Now tell me, who's logic makes more sense? Yours or the rest of the world?
