For Christians, it's "Love thy neighbor as thyself," of course.
In your case, though, I'd recommend "Sober up, and sleep it off" as a good start towards that laudable goal...
Oh, so you have peeked in the Book, then, or heard it somewhere :-)
I'd be so interested in hearing your (clever, I'm sure) justification for behaving in exactly the opposite way. Will you define "love" as ridicule? Will you claim that only some people are "your neighbor"? Will you excuse your haughtiness as the way you "love" yourself?
I can't wait to hear your response...
And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
