I didn't say that understanding and agreement are the same. What I wanted was for that user to understand where the other side was coming from, and acknowledge that, and if they still had a different opinion, then okay, but I just wanted to try and explain the side I'm on in a less directly hostile way than the other commenters are.
You make some logical points, I won't go into my opinion since it already seems clear, hope you have a nice night, genuinely, people should be able to discuss this stuff maturely.
