Say whatever you want, he's ego blind. It's a thing. They can only decode what suits their own primitive sense of self worth, everything else flies over their heads. Your art is the magic mirror. In it they will discover themselves.
"Alba, when your inner good wolf is the boss of your inner bad wolf, you will become a hero greater than you ever dreamed possible. Yet that kind of courage is earned every day through humble, giving, selfless, love. When you have done that, you will have a very different kind of ego from the one you have seen in others. The good wolf self "ego" is flexible and seeks to lift others up, to see them become masters greater even than yourself. Value yourself enough to take on this struggle. Mature. Gain self control. Be a role model of love. Learn that ego transforms into solid self respect."
Know thyself, Panadora. If you are all "hung up" on yourself then you hung up on yourself. Pick up that phone. Dial into your real self and figure out your true feelings. Figure out why you react and respond to situations the way you do. In there is real personal freedom and the key to a good future for you and others. Bon voyage, a bientôt mon amis.
The extremist lives in a bubble, a delusion, that takes what is a fragile and weak ego and creates a fantasy world in which they are important or strong. Thus their Achilles heal is to take apart this twisted and sick alternative reality. First, the idea that others want what they want, or are secretly hiding hate, or would follow them if the other options were removed... this needs debunking. Secondly, other options for building real self esteem and an actually strong ego need to be put into motion, otherwise they will seek the "Bonnie and Clyde" exit strategy. They need to see that even if they were the last asshole standing the "sheeple" (as they see it) still would reject them - but - if they do "xyz" then they can gain true acceptance and join the "herd" instead. Countering extremists is not carrot and stick, it is cold water and a warm towel.
