The main reason is to acknowledge that I disagree before I speak highly about a certain part of Reddit.

It would have been unclear and implicitly sound like I agree if I didn’t include that.

On the contrary, it's an objectively true statement, and everyone already knows the reasons why. Therefore, explaining it here is what would be flamebaity, since even those that know the reasons still try to disingenuously pretend the reasons aren't valid. What is valid is the point made, since it addresses a point of the previous comment directly.
