i understand what you are saying..but i think religionists is the wrong word.
that word speaks of more attention/focus on the rituals,doctrine,etc rather than an actual focus on God.
and consider human nature, anything can be corrupted..no matter how ideal.
so its really not a matter of starting some new ideal movement as it will become corrupted also..
i think it is just a matter of fighting the misinformation/misunderstanding.
unfortunately..some ppl love their own understandings,and will fight any ideals to the contrary (both theist and non-theist)
so its not a matter of convincing ppl that religion is in error,(most ppl know this)
bad mouthing/trashing religion only communicates your opinion of it,it does little to encourage ppl to rethink religion.
