Now that is an outright lie. They had brutal, public arguments, killed one another in duels, and started a shooting war with the British Empire. They were not effete GOP cowards who speak like prudish little old ladies. From the newspapers of the time founded by the political parties:
John Adams was called a "hideous hermaphroditical character, which has neither the force and firmness of a man, nor the gentleness and sensibility of a woman." He was called a fool, a hypocrite and a tyrant.
Jefferson was called "a mean-spirited, low-lived fellow, the son of a half-breed Indian squaw, sired by a Virginia mulatto father." He was also called a weakling, an atheist and a libertine.
The rhetoric got so heated that in February 1798, two congressman got physical.
"There was a congressman from Connecticut — Roger Griswold — and he was one of the Federalists, and there was congressman from Vermont, named Matthew Lyon, who represented the Democratic-Republicans," Daniels said. "And they were polar opposites in terms of political views. And one day, it just boiled over."
Daniels said Griswold insulted Lyon. In return, Lyon spit in Griswold's face.
But it took two days for things to really escalate.
"Griswold came into the House and started to beat on Lyon with a wooden cane," Daniels said. "Lyon ran to the fireplace and grabbed a pair of tongs from the fireplace. And they actually dueled on the floor of the House with a walking stick and a pair of fireplace tongs."
Daniels stresses that these fights weren't a regular occurence. Brookhiser also says that duels were not uncommon.
Hamilton had been part of at least 10 duels over that 10-year period and was killed in the last one by William Burr.
We were discussing written language over the Internet - where people are anonymous, can’t see one another, and are judged simply by their writing.
We weren’t discussing in-person fisticuffs - and I don’t see a lot of capital letters in the quotes you reference, either (as eloquent - relative to the writing we see today - as they were.)
