It is absolutely ridiculous to associate President Trump with the KKK.
The Ku Klux Klan is the name of three distinct movements in the United States that have advocated and employed terrorism—both physical assault and murder—against groups or individuals whom they opposed.
President Trump has repeatedly and forcefully condemned terrorism of every kind.
The first Klan (late-1860s to mid-1870s) was founded in the South by Democrats who were furious that they lost the Civil War. It sought to overthrow the Republican state governments in the South during the Reconstruction Era, especially by using violence against African American leaders.
“Polls show consistently that what blacks care most about today is jobs and economic opportunity. … So far Trump has done more for black economic progress in six months than Obama did in eight years.” – Stephen Moore, Aug 15, 2017 @ The Hill (link below)
The second Klan (1915 to mid-1920s) was rooted in local Protestant communities, particularly in urban areas of the Midwest and West, during a time of high immigration from mostly Catholic nations. It primarily targeted Catholics and Jews.
President Trump’s wife is Catholic; his daughter is Jewish.
The third and current manifestation of the KKK emerged after WWII, in the form of localized and isolated groups angry about the successes of the Civil Rights Movement. The most optimistic estimate of its total membership as of 2016 was a measly 6,000 nationwide.
Virtually every Christian denomination has officially denounced the KKK.
