What criticism of American society did Theodore Weld have?

Theodore Dwight Weld was highly critical of slavery in American society. Weld was so adamantly opposed to slavery that, having been told that by trustees not to discuss the issue, he resigned from his professorship at the Lane Theological Seminary in Ohio.

Weld lectured extensively on slavery and was instrumental in the founding of the American Anti-Slavery Society, for whose publications he also served as editor.

After the 13th Amendment brought an official end to slavery in the United States, Weld founded two mixed-race, mixed-sex schools over a period of 10 years — one in New Jersey and another in Massachusetts.
