If "Paki" is acceptable to use then what other slurs are? Nigger? Spic? Homo? Jap?

Really? That’s the single most offensive word you could call any South Asian person even though it’s specific to Pakistanis and people from Pakistan use it without considering it a slur? It’s the most offensive word for South Asians even though a significant number of English speakers are unaware it’s even an insult? That’s quite a bold claim! I think at this point you’ve overstating your case. I’m not interested in going around and around on this subject, so I’ll say this one more time: we’re aware the word can be used as a slur and we moderate it accordingly. I think the moderation in this case was appropriate, and frankly, since you’d already taken the thread off topic with this gem:

I didn’t think it was necessary to press the point that “Paki” can be offensive. You’d already made that point in much more inflammatory and distracting terms than I would have.
