Some people have unrealistic expectations.
This is just a chat, internet discussions. Its in our free time. Instead of watching TV or gardening we are discussing the Bible.
It does not have to change us drastically or lead dozens of atheists to repentance.
Regarding me, I have learned to discuss without emotions and concentrate on the subject better. I also learned to better formulate my views, some new names of my views

I also learned my own views better (because I needed deeper, better arguments).
I also learned much new information when discussing, because I frequently need to go to Greek or the first church documents etc.
I also practice my English (theological and vocabulary) and Bible knowledge. When some topics return, its a learning by repeating to me.
