“Like...” = “I’m about to explain myself, but need a filler word to give myself more time to formulate the sentence.” “no” = “whoops, couldn’t think of what to say quick enough to avoid an awkwardly long pause; I’d better tie off that sentence I just suggested I was about to start.” I’m not quite sure what to make of “Sorry if it offends you”, but I don’t see how you can get from there to “I’m not even trying to be polite.”
