He's been pushing the same healthcare, healthcare, immigration and labor policies while also defending the idea of democracy and the freedoms that come with it for 40 years. I'm convinced that he really does believe that his policies would do more good than anything anyone else has proposed. (Note: Personally, I'm not convinced that his policies are the answer right now)
There are tons of valid reasons to be anti-Bernie, but, in my opinion, being worried that he will try to become a dictator, take over the world, execute all who oppose him, or commit genocide are not among them.
No. He completely flipped on both immigration and the Second Amendment. He also used to be in favor of free speech and hasn't said a peep about cancel culture.
He's also stayed mum about intersectional theory which contradicts his labour / marxist viewpoints.
No. Bernie has not been consistent.
