"(This begs the question: Why are most examples of oppression from the past?)"

It doesn't beg the question, it may raise it. To beg the question means to avoid it.

“It doesn't beg the question, it may raise it. To beg the question means to avoid it.”

Umm,.....I think that's wrong. According to the dictionary:

beg the question
phrase of beg
1.
(of a fact or action) raise a question or point that has not been dealt with; invite an obvious question.
“some definitions of mental illness beg the question of what constitutes normal behavior”
2.
assume the truth of an argument or proposition to be proved, without arguing it.
