I'm sorry, but that is delusional. It is not possible for humans to forego emotion in favor of logic.

It's really just about giving yourself enough time to think before you respond. That's the entire difference between a reaction and a response. You can use dialectical and cognitive behavioral therapies to help develop the tolerance to do that. Mindfulness and meditative practices like those in zen buddhism have proven helpful to me as well. Perhaps you're taking an extreme interpretation of my using the word "logic" and instead you could use "wise mind" or even just "considered thought" as the response in lieu of an emotional one.
