PROTIP: SHAME PEOPLE INTO SHARING YOUR BELIEFS
It's the best way to make sure everyone totally listens to you.
While doing it, don't forget to pretend you are on a higher level intellectually. It is also of vital importance that you disregard the other person's life, that you bring in loads of numbers you have no capacity to understand, and a good old 'you are worst than [genocidal maniac of your choice]'.
If a concern regarding your belief is brought up, just armor up with appeals to authority and repeat this mantra 'We are right. We are rightful. We've done no evil. We've promoted no evil. We are life. They are death.'
Now, if the situation evolves and turns out you were actually wrong in blindly trusting the words of people-who-have-their-jobs-fortunes-and-influence-on-the-line-which-they-are-desperate-to-keep, don't worry. You can still parrot these people's new words, rinse and repeat every time they are found out lying. After all, how could you have known, right?
No proliferation of the right ideas would be possible without generalization. Remove individuality from all equation, you don't have time to waste actually listening and discerning a nail from a screw, you have to shame as many people in a day as possible, your group requires it. The future of humanity on the line, surely. Individuals don't matter, only the categories in which you can fit them do. If you can't fit them in the proper categories, then you are not putting enough effort. Deform anyone who requires deformation if you must in order to make sure those who are not Us are Them. You can't be heard listening to a discernable voice. To you, it should all sound like the desperate screeching of an injured beast. It just doesn't know better, even if it does.
Once again, always repeat:
"We are right. We are rightful. We've done no evil. We've promoted no evil. We are life. They are death."
