It is so very simple, but it can make a huge difference.
2. Question Stereotypes...
3. ...Especially That "Men Are From Mars, Women Are From Venus" BS
Noooooooope. Nope nope nope. Holding up the overarching belief that "Well, men and women, they're just different. They're like cats and dogs"? That's at the root of the whole problem. If I have to hear, "Well, women are just really catty" one more time from anyone, regardless of their gender, I will lose it. It is so lazy to fall back on platitudes like that.
4. Hold Each Other Accountable
Who else if not your friends can you rely on to be an honest mirror? We hold a lot of internalized prejudices — it's kind of unavoidable. In order to address them, and subsequently fix them, we need other people to sometimes be an unbiased third party and say something.
5. (Share The Emotional Labor)
This is a gendered action. Women tend to be socialized to feel like they have to do the full amount of emotional labor in a relationship, especially when it's with someone who's male. Reject that. Be on the lookout for those tendencies. They're not necessarily verbal. Friendships should be some of the most equal relationships we'll ever experience, and one person doing all the heavy lifting while the other stands idly by is, uh, no good.
6. Make An Effort To "Call In" Rather Than "Call Out"
Getting immediately aggressive and condescending will, 99 percent of the time, make people tune you out. Treat your friends (and everyone, honestly) with respect. Even if you don't agree with them, make an effort to understand where they're coming from, and work your way from there.
7. Send Each Other Resources
The best way to learn? Read stuff! Google it! And then share the wealth!
8. And Discuss Them!
Learn to love intellectually stimulating conversations with friends about challenging the gender binary! They are the best! You will become a better person because of them!
