I don't have much time but I wanted to weigh in on this topic too.
It seems that this conversation is stemming from the perception that we have no choice about or control over our feelings in the first place.
I would disagree with that. I have personally learned that indeed, my feelings ARE my choice. I have a choice about how I'm going to feel each and every day I get out of bed. And the choices I make about how or what I feel then set the tone for every interaction I have throughout the rest of the day.
