Marijuana legalization was also legalized via slim majorities at the ballot box yet - I havent heard of one legal challenge to the initiative and it's implementation.
Why is it that each and every same sex marriage initiative was challenged and over turned and not one legalized marijuana initiative?
That is fairly easy to explain. The order of the day is all that is good is to be looked down upon, covered up or diluted, smothered, destroyed if possible, mocked, diverted from, and any other method that can be envisioned to discourage morals, values, virtue, etc.
Marijuana legalization furthers this movement away from morals, values, virtue, truth, etc. just as striking down marriage laws in favor of sodomy. Actually its in favor of going after religion truth be told, they could care less about those engaged in those acts. There is a movement whether consciously or unconsciously (I suspect a bit of both) geared toward those ends among other things.
I don’t know if you believe in God, but I do, and I see a spiritual war behind all this. This is really the only thing that makes sense at this point to explain what is going on. While one can point out to some organizational efforts geared toward all this, there are also large elements that have very little in common with each other and yet there is lock step agreement with all this and yet very little in the way of actual communication. Its like they have evil whispering in their ears all at once, which can only be explained by the spiritual side of things.
