Many people hate many things and say they'll never do that, buy that, etc.
For example, perhaps you hug trees and would never buy an SUV and then you have three kids in five years, all of whom need to be in car seats and your Prius can't fit three across the back. So, you buy a hybrid Toyota Highlander. Ahh, you now have an SUV and have become what you hate.
In that vein, I used a leaf blower today. I have become what I hate. I have no defense, but I am pretty sure I'll never do that again. My hands are still vibrating and it's been almost an hour since I stopped.
