Everything I'm reading suggests that he was a violent guy with serious anger issues, but that he never had any special dislike for Black people. The fact that people didn't like him doesn't say anything - in fact, not being racist against Black people would be more likely to cause you issues in White society in the early 1900s than racism would.
What is the "juelzing"? Gandhi was a racist by his own admission for the first half of his life (definitely in his 20s, and to a degree in his 30s), just like virtually everyone in the 1800s who were educated through the British educational system. Due to his friendships with Black South Africans, his firsthand witnesses of the bravery of African freedom fighters during the South African Wars, and his introduction to the budding anti-racist literature that started coming out around 1900, he converted to a very strong antiracism by 1911. For the last 40 years of his life he consistently fought against racial discrimination across the world and for the independence of every African peoples from White colonialism.
To insult those who think positively of Gandhi's rejection of the racist beliefs he had been taught and turn towards antiracism is to insult Martin Luther King Jr., W.E.B Dubois, John Dube, S.S. Tema, Nelson Mandela, Hubert Harrison, George Washington Carver, Marcus Garvey, Bildad Kaggia, Jomo Kenyatta, Nnamdi Azikiwe, Albert Luthlui, Kenneth Kaunda, Joshua Nkomo, Kwame Nkrumah and other great Black leaders who corresponded with him, were inspired by him, or considered him their friend. Dubois, Dube, and Tema in particular knew Gandhi extremely well and corresponded with him extensively, and MLK Jr was so deeply impacted by him that he traveled to India well after his death just to walk the places he walked and meet the people who had known him. A full 1/3 of the MLK museum at his childhood home in Atlanta is devoted to his impression of Gandhi.
Understanding real history involves dealing with the complexity of real people. Every "hero" of the past made serious mistakes at some point in their life, some of which were a product of their society and some of which were their own personal failings. Those who rejected their society's ways in order to do something better are the most impressive to me, and those who realized the error of their own ways and changed themselves to become better are impressive as well. I have more respect for Gandhi, who was raised in a by-default racist society and started with those assumptions but then became one of the first major leaders to flip on that and speak out against it, then I have for any random 21st-century person who has always spoke out against racism just because that's the default position now, but would have been just like the racists if they were born under British rule in 1869.
