How many times did you say as a child "I hate you!" and feel sick to the stomach afterwards because you'd used the word 'hate'? Maybe it was just me, but I doubt it. Now think about how often you use it. "I hate that idea." "God, I hate this, it's vile." "I hate him so much, I hope he rots in hell."
I use it all the time. I use it about Donald Trump on a daily basis. And I can feel the shadow creeping in on me, because I have forgotten how wrong it is to say it, and by saying it, to put thought into practice.
