Hmmm, this is an interesting thread. I wonder if it is a cultural difference or something, but this is a different meaning for 'enabling' than I was familiar with until I read this thread. Learn something new every day!
Where I come from enabling someone would be like examples:
A sister gives her drug addict brother money to pay his power bill, even though she knows he will just go spend it on drugs instead. She is enabling his drug habit, instead of reasureing him that she loves him but not giving him money. Allowing him to hit rock bottom and realse he needs help.
A father supports his adult daughter paying for her shopping for designer clothes, and doesn't encourage her to get a job and pay for her own things. He is enabling her to not take resposability for herself.
A mother knows her son doesn't do his laundry, so she goes around to his house and does it for him. She is enabling him to continue lazyness, or uncleanliness because he knows he doesn't have to learn to do things for himself.
So a poster here on AD could be enabling by the other definition that I already knew by maybe...
Knowing that someone is giving out bad information, or behaving badly, but instead of correcting them, or provide guidence on better ways to address people, they instead encourage them to post more silliness or provoke them with teasings knowing they will upset more people or make more mistakes. They're enabling them by giving them an audience for their bad posts, but not encouranging them to improve their interactions with others, or setting a good example.
This meaning I am familair with is more like, knowing when to step back and let people learn for themselves and grow, instead of just allowing or even helping them to continue in a destructive path.
I'm interested to learn of the other ways you would call someone enabling. These are new to me! Very interesting reading, thank you.
