...is that if the masses read it they would realize that all their governments are fascist and that Hitler's compilation of ideologies are alive and quite well.

Well maybe that would have been the case 30 years ago. I don't know if the average westerner has the vocublary and attention span to finish the first chapter these days.

Mein kampf is overrated tbh, Instead you should read the industrial society and its future by Ted Kaczynski.
That book could entirely change your prescriptive on the world as a whole and it's current state, and I would recommend to read it several times to fully comprehend the issues it's discussing. Just don't kill anyone after reading it, but instead work on eliminating the techno-industrial capabilities people imagine benefit them by propaganda until they realize how serious the situation is, just like how they're realizing right now what is the Jewish problem.
