Where to begin...
If the ponies world was accessable to us, "humanity" would probably plunder (at some point) and worse...
but as for them "helping" us? they already are! thats the messed up part...
i grew up on Fraggle Rock, Jim Henson, and I LOVE MLP:FIM because it is very much like Fraggle Rock!
if you have seen the series then you know, it was about forgiveness, peace and tolerance... there is a lot more to it than that but you don't need me to rant about another TV series...
My point is, look at all the good, and all the bad... because of how "generalized society" views good vs bad, and the reality of them (not saying I know for sure myself...) its "inconceivable" (Princess Bride) for the whole of humanity to just "become good"...
I could say that humanity is humanity because of its chaotic nature, without it, we would not have most of the drives we have...
we all just need to be patient, and hope the love and wonder of our MLP and FR shows finally starts to have an "effect" beyond people as children.... Bronies may be the first step towards this....
