Rape culture is schools telling victims not to report rape because it might reflect badly on the administration. It's kids being taught that sex is some all important milestone and that somehow you're not living if you don't have it asap. It's women's testimonies being disregarded because the accusation could "ruin the rapist's life". There's no instant fix for this mindset. All we can do is start from the beginning. Teach your children about consent. Take people seriously when they report rape or harassment. Visit RAINN.org for more info.
