It's become a new fad now for millennial females to shout out that they're a feminist, because they think that that's what it takes to make them a strong, empowered female. However, just because you're educated and you don't need to depend on a man, it doesn't mean that you're some die-hard feminist that Susan B. Anthony would be proud of. In fact, many of the girls who claim to be "feminists" would be major disappointments to Elizabeth Cady Stanton, because they do some of these things on a regular basis. So, just to get things started...you're not a real feminist if you....
Isolate yourself from other female
Saying things like "I'm not one of those girls" is negative towards other members of your gender. When you put yourself in a separate group from the regular, stereotypical girl, you are supporting that stereotype and you're agreeing with the fact that it's negative to be a female. That's the exact opposite of what a female is supposed to do. You aren't just supposed to care about yourself and bettering opportunities for yourself. As a feminist, you are taking on the responsibility to make things better for women as a whole.
If you date a guy who supports rape culture
If you can stand by and support a guy who makes comments like "Well, of course guys were gonna get grabby with you. You're dressed like that, what are they supposed to think?", you're not a feminist. If a guy ever looked at a girl and made comments like that, and you know that those comments were made, there's no reason that you should be wasting your time with that guy. Because, newsflash? Guys like that don't change. It's not some bad habit they need to break. It's an entire mindset. They actually think that if a girl wears leggings to a party, she's asking to be assaulted and that's not okay.
If you think that "girl code" is a real thing
Whenever you ice out some girl because she "breaks girl code" by dating a guy that a friend dated in high school, when relationships aren't serious, you're acting like the girl is the problem. You're helping create a society where guys can slut-shame girls. Yeah, dating a friend's ex is harsh, but it's not some unforgivable sin. If the breakup just happened and wasn't the result of cheating or a harsh, brutal end, there's no reason that after a certain amount of time, that guy can date any girl, regardless of who her friends are. Especially when the guy was friends with the group of girls prior to the initial relationship. Doing this just pits girls against one another and if progress is going to be made, we need to work together.
If you participate in Slut Shaming
If you think that it's even a little bit okay to call out another girl for her sex-life, then you are not a feminist. Women are totally free to do whatever they want with their bodies, because they're people who are capable of making their own choices. Therefore, if they want to sleep around or settle down, that's nobody else's business. If you think that it's okay for you to judge some girl for her life choices and to judge her negatively about it, then you're not a feminist.
If you Weight-Shame
If you judge another woman based on the way that she looks and you try to act like a body is the most important feature that a woman can have, you're negating so many feminist movements. Character is far more important than appearance, so why are you trying to tear down a person for not being a size zero with a killer booty and a full chest? It's not being a feminist if you're judging a woman for her appearance or some other irrelevant measurement. Integrity is what really matters and if you do this, you clearly have none.
If you go to a man because they're "stronger"
If they're actually stronger, that's fine. But, going to a guy to open a jar when you're in a room full of people of both genders, it's sort of ridiculous to go to the male in the room. I know plenty of guys who are weaker than girls that I know. Being a male does not make you stronger than every single female in the world. Evolution has taken people far past that traditional mindset that women are incapable of doing anything that involves physical strength. Assuming such things is so anti-feminist that it's not even funny.
If you say FEMINIST like it's a bad thing
Acting as though it's horrible to be considered a feminist is the exact opposite of what a feminist is. You should be proud to fight for gender equality. When you act like it's a bad thing to be labeled a feminist, you're playing along with the idea that it's a negative thing to believe that a woman is an actual human being who should be treated as such.
