That is an ignorant statement.
The original Ku-Klux Klan, the one that targeted freed slaves (along with the Union army and Republicans like my ancestors) was not in the least anti-Catholic (or anti-Jewish) and did not burn crosses. In fact, the original Klan had Catholic and Jewish members.
It was the twentieth century Klan that was anti-Catholic and anti-Jewish, not the original "terrorist wing of the Democrat party."
Now THAT was an ignorant statement!
Klan apologetics is a new low even for the Religion Forum. There are some theories that the Second Klan of the 1920 was more anti-Catholic (because there were more Catholics following the influx of immigrants from Catholic countries in the 1870-1890's, but that is wrong. Catholics trouughout the South in the Reconstruction period were largely immigrants, carpetbaggers, and Republicans.
