Summary
This quote humorously suggests that understanding and communicating with trolls, who are often associated with rude or offensive behavior online, is a simple task. It implies that engaging in pointless arguments or negativity requires minimal effort and intelligence, as it mainly involves resorting to primitive and uncivilized behaviors like pointing and grunting. Essentially, it highlights the idea that it takes little skill or knowledge to engage with trolls, and perhaps it is best to avoid wasting time on such interactions.
