Should history be taught from the “perspective” of marginalized groups?

[MarkD]

Who are all of the marginalized groups? How many different kinds are there? If we're going to do this, shouldn't we include ALL groups? Would that include illegitimate children?

In 1994, I discovered that there was a great deal of case law, from the SCOTUS, that dealt with the subject of state government discrimination against illegitimate children. Until that year, I didn't even know that there was such a thing as government discrimination against illegitimate children. I didn't know that there used to be laws which said things such as "Illegitimate children, though duly acknowledged, cannot claim the rights of legitimate children. ..." And when I learned about this, I read that Justice William Brennan argued that laws such as this did not serve any legitimate purpose, and these laws were based on nothing more than "the untenable and discredited moral prejudice of bygone centuries which vindictively punished not only the illegitimates' parents but also the hapless and innocent children." It took me a while to figure out what Brennan meant by "moral prejudice."

So should history be taught from the perspective of illegitimate children too?
