“As with the Christian religion, the worst advertisement for Socialism is its adherents.”I don’t know if expressing it in this form originated with Orwell, but the sentiment has, I’m sure, been around as long as there have been Christians. Why? Because there are always among us the immature, the untaught, the uncommitted, and those whose professions of faith are false for one reason or another. There will be until the Lord returns.
— George Orwell
Small consolation that those who express the sentiment compare it to the insincerity, incompetence or general undesirability they observe in the adherents of other philosophies.
