“If you want to lose friends and alienate people, attack their identity. Belittle them (“I told you so”). Ostracize them (“If you’re not with us, you’re against us”). Ridicule them (“You’re not a real ______”).
But if you want to win friends and influence people:
Link your agenda to their agenda.
Explain why your cause furthers their cause.
Instead of drawing a small circle to exclude people, draw a bigger circle to include them.” Ozan Varol
