Well, regarding clear thinking. I suppose you refer to being in able to take a seat in everyone's physical position and sensory observation, imaginary. Rather than spreading words on behalf of psychonauts too much as a solution.
I found out that 'switching brains and life history' fictive, can do a whole lot to bridge the boundries between your inner vision and those of others. It'll most likely decrease your believe in what's possible but it's realistic at least.
It is double-sided that we focus our minds on area's with people in it who live in hate, fear and war the most for almost their entire life because we feel we have to offer them a solution that's so wonderus that they'll wake up because they need it the most of all.
The distance is so wide, but everyone who has gotten himself into the entheogenic awareness, obtained in a system of wealth and peace tends to believe he's pretty damn close connected to everyone everywhere. From our seat in our head, this is true.
Like the Palestinians, they are other outer side of our culture and as Terence pointed out, culture is your operation system. We can't even pull some of our close friends into our vision. So why would we be in able to even point eyes, which have been raised with fear, anger and hate for their entire life, into the direction that probably suits the human mind the most? Spreading any metaphor will make us just another pawn. Their seat within their consciousness in completely alien compared to ours, and vice versa.
In politics, you'll encounter a lot of pricks. But what makes someone a prick? Yes, the contrast of believes that are not in line with those of ours.
An entheogenic awareness is more a luxury and ego position than we probably would like to admit. It requires the right environment choosen by fate, a stable peaceful youth, encountering the right information, access to substances, and luck.
All you can do is expressing your appearance, connection with life, feelings and emotions, art, speech, text, with the hope that people will look through it and then start to fish for further interest with their free will. Other than that, you have no priviledged position in any debate, wisdom, solution, capability or right within the world
