As for -phobia, I believe it has indeed taken on the meaning of "hate," as gift horse pointed out. The inelegant "homophobia" comes to mind.

i think phobia (fear and loathing) has come to often just mean loathing--and that it is used because it 'neatly parallels' phile.. as in anglophile..--it sort of sounds right, even if it's not 100% accurate.
