A bully in our neighborhood bullies others. Instead of condemning him, we tolerate him, afraid we otherwise might be bullied next. Eventually the bully builds an army: less of willful supporters than of those who fear him and are afraid to oppose him. His only method of building support himself is to scream about even bigger bullies elsewhere—from whom he claims to be protecting us—so we'd better be on his side, or we'll be his enemies, too. This is how opposition falls apart. This is how a party falls apart.
