It appears you are letting your past personal experiences distort your judgments about me. It’s ok. I understand this. It’s natural but it makes it hard to have a discussion about whether or not it’s the case that everyone can learn algebra.
You made a statement that the way to pass everyone is to do my job. Clearly you have not taught much in a classroom with a wide variety of students. Consider the possibility that you simply don’t know anything about the craft of teaching other than your very limited experience of being a student and that as such you should be wary of making negative conclusions about me.
