I think its pretty common that when students are divided by "ability", especially later on in middle or high school, it can weigh pretty heavily on the students in the "lower ability" classes. Its essentially saying "we don't expect much but you need to be here."
This system works out very well for bright, academically inclined students, sure. But it sets a structure of expectations that don't motivate what could possibly be great talent, but we wouldn't know because they didn't bubble in the right answer.
If only there were some sort of world wide network of information where women could write about their experiences and share them with total strangers. I guess we'll have to leave it up to the occult for now.
Have you read Steven Pinkers "The Better Angels of Our Nature"? In it, he argues that even though violent crime is on the decline, and is at a historical low, the perception of violent crime is at a historical high, because we are bombarded with stories about the few violent crimes that happen across the globe.
Could it be the same pattern at play with blogs on the internet?
It would be entirely fair to say that sexism is also on the decline, I don't dispute that. For example, my father can no longer sell me for 3 goats (without my consent, of course). But this doesn't make it a non-issue, just as violence is not a non-issue. Just because a program is throwing out fewer errors doesn't mean its fixed.
Its only a matter of time before someone decides to upload videos of people rejecting them at bars with accompanying "woe is me" commentary and resulting subreddit.
