Does Dr McCoy hate Spock?

I have to ask, is there any truth to the rumor that Dr. McCoy harbors a deep-seated dislike for his crewmate, Mr. Spock? It's been suggested that their differing personalities and approaches to problem-solving might create some tension between the two. Is there any evidence to support this notion, or is it all just speculation fueled by the fiery debates they've had on occasion? I'm genuinely curious to hear your thoughts on the matter.
