I think I know what you’re getting at.
It’s true. We are not allowed to mention certain things. We are not allowed to talk about certain issues with schools, such as disciplined problems.
We are not allowed to talk about kids who come from a culture which doesn’t value education, and how parents of those students do not value their education.
Instead, we talk about side issues such as an alleged lack of funding for schools, as being the root of these problems. It seems to be the default argument nowadays, that somehow we are shortchanging schools , and schools would do a better job if only we spent more money on them.
You are correct.
