Terrified? That's your biases being projected. Communism fails under its own weight. You're reasoning for socialized healthcare is fundamentally flawed and you can't logically defend it. All you can advocate for is taking from those who have and giving to those who have not. Would you prefer we call it theft, confiscation or possibly Robin Hoodism? The term for what you want is Communism. Look up the definition. The fact you won't use the correct terminology for what you advocate is on you, not me.
Single Payer is nothing more than a polite euphemism just like pro choice is.
