'Live and Let Live' - Basically, social liberalism and progressive attitude. If it isn't causing harm, spreading hate, whatever, let it be. Obviously there are some issues where such concerns are muddied (like the pro-choice/pro-life debate. I'm pro-choice, but I can understand the concerns of pro-lifers in situations where the hypothetical child would likely be born healthy).
Incidentally, my nationstate was a 'Scandinavian Liberal Paradise' at one point, though I think it has since downgraded slightly? Think I'm in the top 10% in regards to overall happiness and for low-crime stats, and there isn't much division of wealth between the citizens (whether you think that's good or bad is up to you, but I think that my fictional nation being quite happy in general is a good sign, I think it's true in progressive nations, a-la Scandinavian region countries. High taxes, but high happiness index).
If you could be the deity of something specific (like, 'fire', or 'peace', or 'electronics', whatever), which would you choose?
