I think its time to get the same attention from loving acts.
Maybe in the coming years the human psyche will have evolved enough - or enough individuals will have become conscious enough - for loving acts to grab headlines. I don't see that we're there yet.
However, you can develop your own spiritual garden, you can live a spiritual life with like-minded people. I doubt you'll ever find a group, or found a group, where everyone will agree with every detail - but through tolerance and compassion you can hang on to your own ideals while making a difference for others.
You say you've already rejected all the other groups out there as falling into lies. So your choices are somehwat limited if you're set on working within a community:
1) Accept all groups are flawed, but join one anyway. Work through their existing resources and networks to make the world better.
2) Create a group of your own. You may want to live in an area where there is already a sense of reaching toward human potential - say, San Francisco as opposed to places in Virginia or Arkansas. Though nearly every place has a community of intentional living somewhere.
3) Join a "monastic" order or communal living arrangement and just be surrounded by others on an inward spiritual path. Perhaps an ecumenical, non-denominationl arrangement.
It's hard for me to separate what might be several things going on: the terrors you have seen likely have had a large impact. There seem to be a couple different needs - to be around conscious people, and to make a difference in the world. I'm not sure if you need to be around loving, conscious people as just a way to further your own healing, or if that really is how you want to express your contributions to the world.
It may be that you need to heal yourself first. It may be that your desire to be loving to the world is an expression of your need for loving yourself, to love yourself. THat's always a good way to build a foundation for a loving life.
I think it may be that with focused healing it will become more clear how to make your contribution to the world.
It becomes such a routine that I hate to say it, but perhaps some individual therapeutic work might be helpful to put things in order for you...
Cheers!
