More times than I can count, I have had my questions on Math Stack Exchange criticized and condescended to in the comments and sometimes answers. The usual theme is that my question is dumb, makes no sense, and isn’t of high mathematical quality. Maybe it fails to express the relevant notions in a mathematically canonical way; maybe it fails to speak of mathematical ideas with the necessary precision of quality mathematical argumentation. Maybe the question shows ignorance of math, or difficulty in understanding math, or has mathematically false assumptions buried in it.
This is obviously a ridiculous criticism of someone who is a beginner in mathematics. It is also pointless and letting snide and trite armchair egotism crowd out the actually valuable potential of this site to help people learn more about mathematics.
I choose not to express myself delicately as an expression of the general atmosphere I have come to feel using this site, based on the many condescending responses I have received on here.
I believe a good Stack Exchange site does not have this characteristic. I believe Math Stack Exchange has lagged behind many, or most, of the other SE sites in cutting out the pointless irascibility that some users have towards people who are not as good at math as they are. I remember maybe ten years ago, Stack Overflow used to be like that, but it got much better. There are loads of other SE sites with extremely positive, constructive, engaged, involved communities of people that try to help the questioner figure out what it is they want to know, instead of penalizing them for not already being good enough at math to be able to answer the questions they would otherwise not be asking.
I believe it should be explicitly incorporated into the site guidelines that you should try to help questioners to formulate their questions better, even if that requires digging and extended conversation and asking lots of clarifying questions. That’s what good tutelage is. And if we want to talk about intelligence, I personally think someone who doesn’t realize this is actually pretty stupid.
