Edit: We've hit the end of the reply chain. I see your point about both the opening and closing sentences. Is there any way to say the first one without coming off as hostile? My goal/point was trying to demonstrate how patently wrong the earlier statements were.

The evidence or examples you provide should make that clear. Unless you have very strong irrefutable evidence, I would hesitate making any absolute statement declaring someone wrong. What does it gain you? No one likes to be told outright they're wrong. The goal shouldn't be to score points: it should be to reach common understanding.

If this is something you'd like to cultivate further, you might find the references in my profile useful. I refer to them myself regularly.

From my unsolicited, third-party perspective, two things jump out at me.

- You could do without the first sentence entirely.

- The insinuation that the parent is possibly a shill (an Uber employee)

The rest of it is fairly neutral.
