I agree, but I'm afraid the argument that the post is making is not based on a logical series of steps. It doesn't follow the typical convention of observation, problem, evidence, conclusion. The post is substantially an emotional outpouring and a call to action. This changes the dialectics.
If you're going to create a central claim that is solely Pathos based, the tone and semantics of how you do so become the most important thing in your argument and, to your point, this is why this post comes off so _wrong_. The post author failed at convincing this audience in large part because of their tone and semantics.
There are indeed discussion-worthy claims in the post, and they're discussed elsewhere in the comments. Why hijack the top comment to change the subject?
I use discord, I have a mild color anomaly in my vision, and have had problems reading low-contrast elements in the UI. Discord's update gives us a useful example of a major release that violates some dark mode design best practices.
