There must be an infinite amount of attempts to separate "emotions" and "feelings" @Abraxas . Notably, your "emotions happen, but feelings are a decision" isn't what's often proposed -- emotions as bodily, involuntarily reactions, feelings as (equally involuntarily) follow-up in the brain -- either. And given that there can be feelings without emotions, in the aforementioned definition, this, too, has issues. As far as I'm aware, there is no full consensus even in science.
Anyway (also for that reason), there is no good reason to separate them in everyday talk, and even threads such as this, when it's clear what is meant. Conversely, it very much is relevant to be precise in terms of quantity, because that is where the actual difference is. "Emotions happen", yes -- but the scale matters! That's where all the information is. "Everyone experiences emotions/feelings" (or "Feelers also ...") is equal parts true and pointless, it yields no insight.
