Ive no doubt theyd complain, and in my view it would simply be whining, as you note Politics ain't softball!
Getting back to the thread topic, if the LDS began running ads slandering the religious denominations who supported the other side, or disrupting their religious services, Id suggest theyd be worthy of condemnation in the former case, prosecution in the latter.
I have no problem with condemnation or persecution of vandalism. My point is that the constant and repeated whining on FR by mormons and mormon defenders is notable, since they entered into this battle and now that they have won, expect the losers to bow and scrape and kiss their rings.
Instead, the losers are using everything at their disposal to strike back which should have been expected, and they have the media behind them. This hasn't ended.
Prop 8 video is a video sensation
There will be more videos and quite probably movies in the next couple of years. Mormonism is going to get more publicity than bargained for, and I expect court cases regarding the seperation of church and state also.
Mormons love for being seen as "persecuted" will be well-fed.
