Yeah, the overt stuff is easy enough to dispel with politeness but the passive stuff is harder. Especially on Reddit, there seems to be a huge number of people that will stubbornly cling to beliefs no matter what evidence to the contrary you provide, and will respond with rude little snarky quips even if you were being civil.

For example, I saw this one video post talking about Bonsai in Tennessee. The person in the video had a thick southern accent and really mangled some of the Japanese terms. One user mentioned this and then was berated by several people defending the person in the video, claiming that's how Japanese people speak too. When I provided a links audio recordings of native Japanese speakers, proving how actual Japanese people pronounce the words, the only responses I received were, "I don't care, I'm still right."

Welcome to the Internet. Where everything's made up and the facts don't matter.
