Etymology: "Asserter" is a plain formation: the verb "assert" with the agent suffix "-er," which marks a person who performs the action. So an asserter is simply someone who asserts. "Assert" itself comes from Latin "asserere," meaning to claim or lay hold of, built from "ad" (to) and "serere" (to join or bind), so the underlying idea is of bringing something into one's grip. The suffix "-er" does the same job in countless English nouns, from "baker" to "reader," and it has been attached to "assert" in the same way. Because the base verb carries the weight of the meaning, the word adds little beyond the notion of the person doing the asserting.
