"All good men wish the entire abolition of slavery, as soon as it can take place with safety to the public, and for the lasting good of the present wretched race of slaves. The only possible step that could be taken towards it by the convention was to fix a period after which they should not be imported."

When you think about the abolition of slavery for example, for the ruling class with the rich white people owning plantations and states, and things like that, slavery was to their benefit. To oppose it didn't make any sense at all on a rational basis. But on a rights basis, on a principle basis, it made obvious, overwhelming sense.
