Why were oppressed populations attracted to communism

The oppressed populations were very attracted to the communism because it offered something that they have always wanted, equality in the society, more or less a horizontal hierarchy.

The communist parties promised to the people that all of them will be equal, they will have the same rights, the same opportunities, everyone will have the same wages. The richer people were not fond of this philosophy at all, but the majority of the population were the poor people, and that seemed very attractive to them.

Unfortunately, the communist parties, once they gained power, were not acting as they were saying they will. In fact, the people ended up being suppressed by dictators again.

the reform movements that arose during the antebellum period in america focused on specific issues: temperance, abolishing imprisonment for debt, pacifism, antislavery, abolishing capital punishment, amelioration of prison conditions (with prison's purpose reconceived as rehabilitation rather than punishment), the humane treatment of animals, the humane and just treatment of native americans, the establishment of public institutions for the care of the destitute, orphans, blind, and mentally ill, the establishment of public schools, the abolition of tobacco use, vegetarianism, health reform, homeopathic medicine, woman's rights (including, at first, especially the establishment of a woman's right to own property apart from her husband and her right to sue for divorce), and the amelioration of labor conditions (including higher pay, the right to form unions, the right to strike, and the demand for limits on the number of work hours, and safe working conditions).
