"If the sum total of your knowledge of feminism comes from looking it up in the dictionary, I don't think you're going to have anything useful to tell me about it." -Thalestris
If an article begins something along the lines of, "Now, if one looks in the dictionary, feminism is blah blah blah," I pretty much know it's not going to be embiggening to the discourse. What usually follows is something like, "Why then, do so many people hate feminism and/or not call themselves feminists?" which is usually followed by a dude-authored mansplainy tone argument answer that is something along the lines of, "Because feminists hate men, are too strident, and/or are too polarizing."
It's a good screening device to use if you're short on time and don't want to read a lousy Article On Feminism Written By (oftentimes) a Non-Feminist or Anti-Feminist.
Consider that my helpful hint of the week.
