lmao no. You are not very smart.
This phrase means: to assume the truth of an argument or proposition to be proved, without arguing it.
It dates back to fucking Aristotle. However, sometime in the past decade, the definition you give was literally inserted into the dictionary because retarded people kept mis-using it. So the dictionary people said fine, we'll include that meaning. Exactly how the dictionary definition of the word racism was changed.
To "beg the question" most specifically does not mean "to raise the question". That is the position of an absolute jackass. Just because the idiots took over and edited the fucking dictionary very recently does not change what the phrase actually means, any more than it changes the meaning of racism when they did the same thing.
