Plymouthean Abby Morton Diaz remembered that the Unitarian and Congregational churches did not support the anti-slavery movement during the 1830s and 1840s.  The Robinson Meeting-House, however, always opened its doors for antislavery meetings and lectures.  

On one occasion, Abby wrote

“I was present at a meeting when it was assailed by a violent mob; stones thrown through the windows are yet to be seen.  My father went for the sheriff, a prominent citizen, but he refused to come.”
