Stalin disliking Kulaks or his personal beliefs towards peasants are not evidence of policy, and it’s the only source you will be able to provide. In contrast, I can bring you quotes by Anna Louise Strong, an American journalist (first woman to get a doctorate in Chicago university) who traveled and documented the USSR, proving that peasants generally supported the Bolshevik movement and government during the collectivization, and how most trials against Kulaks were carried out by peasants themselves.
