I can see how thinking about the choices we have can be empowering. But if T said this in the context of therapy I would experience it as being somewhat accusatory and critical. And as others have said, over-simplifying the issue.
I want T to understand just how hard I am trying and have tried in life, particularly to overcome things which are complete non-issues for others who don't struggle with the same things (people I consider to be normal/acceptable). In that context, if T pointed out that my problems or problematic behaviours were choices, I would think - T doesn't get it at all.
But thankfully this hasn't happened
