I am wondering why it is that questions that are deemed to require opinions are closed or put on hold? But I am also wondering if there is any alternate ways/formats that these types of questions can be asked.
The reason I ask is because for example, I had long ago asked a question about comparing intro classes about algebra and analysis for example, and it was quickly put on hold.
I am fine with that of course, as it apparently was not fit because it needed to man opinions. But what is so wrong about these type of questions? Why is it bad to ask something that may require some opinions? I am just not sure why exactly it is not something allowed. I mean, no one is forced to comment or say what they think on any post. So what harm is really being done?
Would the best suggestions for this type of question just to be, not to ask them here, and try to find a teacher in real life for example?
Here is another example
https://math.stackexchange.com/questions/1316596/is-there-a-standard-order-to-learn-basic-maths
Again, as I noted, I do not even know if it is a primarily based thing or not. And even minutes after opening, it already has votes to close, but with no explanation? I mean, I find the comments helpful, and such, so why should it not be allowed?
Thanks
