No matter what we're replying to, we have the responsibility to remain thoughtful and charitable so that we can have the kind of civil and interesting discussion we're all here for. Assuming that other users are intentionally making false statements is like a short to ground of sorts—it takes a thread straight down no matter what other more interesting threads we might've had instead (https://en.wikipedia.org/wiki/Principle_of_charity).
You're also not the bad guy, we can't moderate everything and it doesn't mean that other participants in the thread are exemplary.
