Fisk means fact check, and fisking is the act of documenting specific statements as factually incorrect and publishing the proof, which normally consists of relevant documents directly contradicting the erroneous statement.
On Second Opinion Blog is an excellent example of fisking. It commenced on January 25, 2009 to fisk, or fact check, the Second Amendment related arguments relied upon as authoritative by supporters of gun control. The specific statements that require fisking are those of the fifteen professional historians who backed up Justice Stevens' 2008 District of Columbia vs Heller Supreme Court dissent arguing that the Second Amendment was not intended to protect individual rights.
The initial On Second Opinion article was appropriately titled, Root Causes Of Never-Ending Second Amendment Dispute Part 1, and the series ran to twenty-four fiskings. That there is any dispute today about Second Amendment history and intent is largely attributable to the fifteen mistaken academics who signed the Heller brief written by historian Jack Rakove of Stanford. Sixteen numbered errors of fact are documented in the Root Causes series along with extensive information essential for proper interpretation ignored by the historians and directly contradicting their Heller brief assertions.
At the top of this page is a link, Fisking Index Page, which provides direct access to each of the twenty-four articles in the Root Causes Of Never-Ending Second Amendment Dispute series. There are also other series listed, and one, Justice Stevens' Train Wreck Of American History, includes fisking of Justice Stevens' dissent itself. The historians' error problems carry right over into the Stevens dissent. Every relevant aspect of the historians' Heller brief and Justice Stevens' Heller dissent are based upon fallacious conflation, historical error, and misinterpretation.
The truth is out there - right here. Find out the documented facts of Second Amendment history. See if your belief system is factually founded and can withstand fisking, or if it has no relationship to reality whatsoever, like the Heller historians and Justice Stevens, and you have been brainwashed.
