There isn't a single derogatory term for white people that has ever offended me. I think most of the terms I've heard are just kind of silly and stupid. I understand where they come from but terms like 'whitey', 'white boy', 'kracker' and 'honkey' are all just dumb IMO
Personally, I think the way the internet's progressive contingent has attempted to hijack terminology to create a sense of guilt is far more frustrating and difficult to deal with. I don't personally feel I'm a 'racist', but that term no longer means what it used to in some circles and there are those that believe I'm institutionalized into corrupt power structures.
I dismiss those as they are applied to me because I don't recall ever discriminating against someone because of the color of their skin. In fact, it seems I get into more random conversations with African Americans when I'm in Chicago than I do white folks. I don't feel threatened by anyone unless they're aggressively posturing on the Red Line or whatever, walking around and mumbling, their voices occasionally rising to bark out some half-decipherable curse.
But still, it is disconcerting that there are people out there that think they can't be racist because of the 'power+privilege' equation. I believe those things can LEAD to racism, and often have, but they are not an automatic and exclusive set of determining factors.
Honestly, being called 'racist' or 'cis scum' are more difficult perceptions to shrug off. And those aren't strictly jingoistic terms like 'white boy' and 'whitey' or whatever.
