Should Republicans condemn all these WN nuts? Sure, but it's not like there's millions or even hundreds of thousands of these losers. Unlike the antifa and BLM goons, the WN contingent is pitifully small and has practically no impact anywhere. Hollyweird and lib rags like to make it seem that their numbers are huge, but the truth is they are tiny.
Nevertheless, the libs will use this incident to tar all Republicans while ignoring all the violence on their side.
There may not be millions of actual White Nationalists, but millions of people are duped by their message and websites. Sites and groups like The Council of Conservative Citizens, VDare, the National Policy Institute, Unity & Security for America, American Eagle Party, American Freedom Party, Conservative Citizens Foundation, Identity Evropa , and more are all front groups for overt White Nationalist and Neo-Nazi groups that dupe millions on the right into following them and sharing their content, usually under the guise of 'protecting western civilization' being anti-immigrant, or something like that.
It is the proverbial camel's nose under the tent. They may not have millions signed up as official members, but they have millions inadvertently linking to them and spreading their cause.
Some of these groups, like Identity Evropa have been very successful in recruiting thousands to tens of thousands of college students to their cause under the false guise of fighting leftist groups.
Every single one need to be called out and rejected.
