Between 2001-2006 I was in secondary school in south London, and let me tell you, what I've read so far on Everyone's Invited's website, was already a proven culture back then. I witnessed it. Imagine how early on this has been going on for (probably even earlier than that!) and only now we are having movements trying to eradicate it now. Thankfully, my parents raised me with utmost self respect for my self and my body, and I wasn't engaged or a victim to these, BUT, I was in a toxic circle and witnessed many boys (and surprisingly even girls) shamed many girls with derogatory names, some even having to leave school because it was too much. It was an incredibly hard place for us, when I look back at it I am amazed that I managed to come out the other end sane.
As many posts have mentioned, you certainly have to start at home, if it wasn't for my upbringing, I probably would have been a victim. I remember a family friend sending nudies online because a guy showed interest in her, it just shows the real problem - self worth. Sadly, we are so driven by our emotions at that age that it really is hard to make the right choices, and being manipulated is so easy. I strongly advise parents to educate their sons, because really it bottles down to this - a lack of respect for women!
