"keep" with certain verbs that shouldn't be used in the progressive?

[dihen]

Is it incorrect to use "keep [verb+ing]" with certain verbs that shouldn't be used in the progressive such as 'want', 'like', 'love', 'hate', and 'know', and sometimes 'be'?

example:
Are these incorrect? If so, do any natives ever say them?

"Why does he keep hating me?"
"Why do you keep liking him?"
"Why do you keep being sad?"
"Who do you keep wanting to do that?"

No, after keep, you can use the gerund in all these cases- it's not the same as a progressive form.
