I review my post history to see replies.
I keep all my logins at the house so no posting until after work. I'll fudge that a bit to explain my browser is a virtual app and I can access it away from home when needed. Not often tho.
In some cases though the reply opens the door to a wider exploration. The poster may make a valid argument or might add nuance which is meaningful. I've found some dialogs offer me a different point of view and my position doesn't necessarily change, but understanding becomes deeper.
But yes, a lot of people's positions are tribal and buried too deep in psyche to be easily changed. Our positions on most things are not based on facts, or at best cherry-picking facts that support our view of the world.
