I have a difficult time differentiating between active trolling and a lack of knowledge/ understanding. u/Moon appears to be leaning trollward. However calling someone stupid, or dumb is ableist or elitist. People have differing levels of cognitive capacity and education. And learning occurs over time, but not by the same linear path for each of us. Ultimately what I'm trying to say is education is better than ad hominem attacks. Also, don't feed the trolls.
