Nothing wrong with the parentheses, I find myself doing that a lot as well. The issue is that the majority of the parenthetical statements are not useful information and not necessary to the point they are trying to make. That compared with seemingly nonsensical abbreviation and overall lack of coherent punctuation makes it an experience to read.
I read the comment above as disapproving of the all of the parentheses in the gp post.
If you remove the posts from people who write that way from the total we are closer to a monoculture.
The difference between having one fewer way of writing and literally having one way of writing is the size of the rhetorical exaggeration in my comment
We don't need speech to be a monoculture for people to understand one another.
