"Hate" is really not the right word in this context, as a lot of them are thrown around casually. Not necessarily due to deep-seated hatred but simply because it is not politically correct to use the words. To gain a sense of being contrarian to the mainstream, to titillate, to watch the reactions of those offended.

For example the "-fag" suffix is applied to everything and practically synonymous with "-person". A namefag is someone who uses a username instead of remaining anonymous. A drawfag is someone who creates original art, it has a positive connotation.

Even when discussing unfair monetary things the term kikes (jews) might be thrown around, just due to the historic association of jews with banking. Even users who present left-leaning positions (e.g. on renewable energy, healthcare or defense spending) use those terms because the associated concepts are ingrained in the conversation structure.

I don't know about /pol/, but other boards use "my nigger" or humorous variations thereof as an expression of endorsement

Use of the words might correlate with the sentiment of the user, but the correlation may be weaker than expected.
