There will be no justice as long as a man will stand with a knife or with a gun and destroy those who are weaker than he is. If we can convince people not to harm mice and rats and cats and dogs and pigs and chickens and turkeys, they will certainly not turn around and hurt human beings. And many great humanitarians, from Albert Schweitzer to Ellen White, from Louisa May Alcott to Albert Einstein, felt that a peaceful society is impossible as long as we are eating and otherways torturing animals. Slaves are being sold, beaten, and killed. The vast majority of good and caring white people do not consider it an issue that slaves are treated this way.
Most people simply look the other way.
The abolitionists agree with all of the substantive proposals of the welfarists. Clearly, everyone should be a welfarist, refusing to participate directly in the oppression and speaking out against the most egregious of the abuses. However, abolition will only become reality as more and more people see the need and endorse it in word and deed.
