It did bother me all the time that they said those thing but were not better themselves. So yes i would like if it was changed (although its manily cosmetic)
How about adding a fifth compassion civic that is neutral (compassionwise), maybe -10% gold? and also available form the beginning.
for balance giving an bonus to fend for yourself? maybe -5% maintaince or +1 XP (the surviving people are stronger).
One other things as we speak of relations. How about a modifier how strong someone will react to different alignment. For example i would think that the Mercurians are real zealots alignmentwise so they would give something like -12 (evil) or -8 (good) if you have the other alignment. But they would not look to intense at your religion as long as you do not be evil (good).
Others could more look at your religion ignoring you alignment alltogether and some would neither look at your alignment nor at your religion or compassion.
