I was learning non-continous verbs once again when I came across a site (I won't post a link to it, it's in russian). And it says that sometimes when we want to emphasize the action, we can use non-continous verb in continous form. And there's an example:
I am hating him!
As the site says, expression above means that someone who said that hates "him" a lot.
I started searching for more info on this topic but found nothing. So my question is: is that right that non-continuous verbs can be used in continous form and if so, how natural it sounds? How often do you say something like this?
