Why might people curse or express loathing for those citizens who support the constitution

Those who supported the Constitution and a stronger national republic were known as Federalists On the other hand those who opposed the Constitution in favor of small localized government were known as Anti-Federalists. Both were concerned with the preservation of liberty, however, they disagreed whether a strong national government would preserve or eventually destroy the liberty. So you could say that those who supported the Constitution were perceived as a threath to freedom and liberty.
