The KKK is effectively a non-entity today in modern society, sure. That's partly because "they" became Proud Boys, Patriot Front, etc. etc. As with the broader societal trends of transitioning away from traditional pre-digital power structures and groups, a rich ecosystem of new white nationalist groups have sprung up in the digital age to feed off the same hate that the KKK used to organize around.

There’s a list of extremist groups now that never existed before.

And At no point in the recent past has there been a breach of security in the capitol like in Jan this year.
