That's a not a true comparison. Boy brains and girl brains get flooded with different hormones at key stages of development which have organizing effects on the brain. Sexually dimorphic brain structures are identifiable before birth and right after birth. Are brains of people from different races statistically different from each other, at prenatal and neonatal times? I don't think they are to any significant degree.So what I am hearing with regards to discipline is that "boys are just more likely to misbehave," does this then transfer to "blacks are more likely to misbehave" since African American students also face more discipline in schools?
Boys and girls do have observable biological differences, starting before infancy. There's a lot of overlap, and biology shouldn't be thought of as destiny, but it is there. A male infant, at certain times, has circulating testosterone levels that are on par with a man at his testosterone peak in his 20's, and a lot of experiments and observations of nature have shown that male and female brains are permanently shaped in part by early circulating levels of hormones at certain key times. So the brain is sexually dimorphic, to a degree. Here are two sources, but the interesting documents are some of the scientific studies themselves. For example, boys with high umbilical testosterone were more than twice as likely in a study to have a delay in learning language, though the definite causation is not fully understood. Expecting identical statistical behavior between young boys and girls if raised identically may not be realistic.
Parents and educators would do well to research teaching strategies that may be doing a disservice to either boys or girls. Biological causes are not an excuse, but the evidence for a sexually dimorphic brain starting from a prenatal time is all there.
I don't think it's necessarily the case that shifting the primary issue to parents from schools is sandbagging the issue. You may have a conclusion that it's primarily the schools fault, but if data suggest otherwise, and people conclude otherwise, it doesn't necessarily mean they're ignoring the issue. It could potentially just be that their conclusion is more accurate.I do not believe there are excessive differences in post pubescent children's testosterone levels. I would suggest that socialization is very much a part of this problem and anyone who shifts the focus from schools to parents is sandbagging the issue. Sure parents shoulder part of the blame, so does media, so do a lot of factors but we are discussing schools. To try to refocus that is to try to gloss over part of the problem.
While I follow your logic with poverty statistics, I think that your reasoning disregards racial discrimination. Essentially, I read your suggestion to mean that the difference in discipline which African American kids face can be chalked solely up to the fact that statistically black = more likely to be poor. I am not saying that poverty does not play a role in the disparity of discipline, I am saying that to conclude causation or even suggest causation is presumptuous.
On a side, poverty and race reading you might find interesting.

I already posted some of the statistics from the reference that Alceste provided, showing a lot of out-of-school differences between boys and girls behavior. Boys are 3x more likely to play a lot of video games, they watch more tv, spend less time reading for pleasure, spend less time doing homework, more time doing sports, and other things. That's more within the realm of the parents to control.
I do think socialization plays a major role that has positive and negative effects on both boys and girls. For girls, I don't think they're often given enough toys and encouragement towards being engineers/scientists, whereas boys are likely given other forms of discrimination in how they are raised early on. I would agree that it's a multivariable thing: parents, schools, media, history, etc. Each one feeds off the other. Seeing as how early some of the observable differences start, I think discounting biology as a factor would be unwise, and then I think the emphasis is on parents prior to and during school years, including the ways they may raise boys and girls differently that can unnecessarily amplify any differences, that positively or negatively affect their performance in various ways.
