Without wanting to cause rancor but in the interest of debating an important subject, I'll tell you why Bernie can accurately be said to be a very divisive leader.
I wasn't a fan of Hillary. As I said, I voted for Bernie in 2016. I have to admit that his supporters were the first push toward my dislike for Bernie but dislike is too strong of a word. More accurately put, "I don't want him to be president" is where I fall in the spectrum of Bernie love and hate.
His policies were always color blind. The "raise the economy floats all boats" kind of thing. As if improving everybody's standard of living will make racism and the effects of our history of racism just go away. Reporters and analysts who are Black quoted civil rights advocates in Vermont as
saying they felt invisible to Bernie. Same with women. Also, he
talked about political correctness as something that (white) people are "tired of" while defining PC rhetoric in a bizarre, twisted and convenient (to him) way. At the time, I took his statements against PC rhetoric as pandering to white people who don't want to believe in such a thing as systemic racism and I still think that. He is from Vermont, a very white state, after all. It wasn't a last straw for me but close to it when he
literally said and did everything to make a mockery of the Unity Tour that he co-led with Perez. He used his time during that tour to tear at Democrats, not try to mend relationships or win over voters who didn't support him in 2016. And that's the thing about him. He didn't try to build bridges, he did all he could to keep them from being repaired. He completely lost me when
he disparaged Barak Obama at a town hall meeting that was intended to celebrate the life of Martin Luther King in Jackson, Mississippi in 2018.
As was said

Sanders can’t lead the Democrats if his campaign treats them like the enemy
You said you can't find anything to read or haven't heard anything to illustrate what people mean when they say that Bernie is a divisive leader. I just gave you four references to explain why the shade Bernie gets is coming the steam that is let out from his own hot air. The strategy of his campaign was to swamp the traditional Democratic Party's base with hordes of "energized new voters". He was running for the Democratic Party's nomination by running against the party. How divisive do you need a person to be before you can see how divisive they are?
I think this country is not ready to enact the policies that the left side of the Democratic Party want. Bernie's "Medicare For All" so-called plan was an albatross hung around the Democratic Party's neck and the reason why we lost seats in Congress this election. That said, I support leaders who endorse those policies. I supported Elizabeth Warren because I thought she could be a great leader and I agreed with her policies. By the end of 2016, I did not think that Bernie could ever be a good president. Since that time, everything he has done confirmed that belief.
