That statement shows that you are low class and ignorant instead of merely being ignorant.
That statement shows I actually know what the word "prejudice" means, as well as "racism".
"Prejudice" + power literally only means you have a prejudice of some sort(prejudice is a very broad term) and you have the power to influence society with it(which can actually be a very good thing, depending on what you are prejudging).
Racism is a specific, racial prejudice.
Misogyny/Misandry is a specific, gender prejudice.
