You may use beg the question to mean either "to cause someone to ask a specified question as a reaction or response" or "to ignore a question or issue by assuming it has been answered or settled." Both uses are established, and the first one is ubiquitous.
One more little matter here: the "to ignore a question or issue" meaning of beg the question has led to a meaning of beg defined as "evade" or "sidestep."
Every authoritative source states that the idiom can mean either
"raises the question" or
"ignores the question", and that both usages are equally valid and established.
