In Germany (At least Germany of yesteryear) you could go to jail for denying the holocaust.
You can’t even say “Well Hitler had one thing right” You would have gone to jail.
But in the US the official party of the KKK still has proud membership. Why haven’t we run these dingbats out of town ?
Why is it ok in the US to say that you’re a “Proud Democrat” and continue voting for them ? Why is Democrat / Progressivism not illegal by now ?!
In the US we have the First Amendment. So you can pretty much say what you want.

Because political parties in the US are like big tents and change identity over time as their members and the views of their members also change. The Democrat big tent used to include the southern segregationists. During the 60's and 70's a lot of people and politicians who used to form this wing of the party switched to the Republican party. But this whole transition took a long time. The Democrat Party platform began supporting civil rights in 1948 and it had already become the preferred party of nonwhite voters.
Even as far back as 1924, at the height of Klan membership, there was strong opposition to the Klan inside the Democratic party. So why didn't they separate into two parties? Probably because they were more concerned with winning elections.
People change over time and obviously neither major party currently has more than a small group of members who believe in segregation or the KKK. But even if they did, it is very rare that political parties are banned in the US. There is a law from the 1950's that made membership in the Communist Party illegal. But I'm not sure if there are any other such examples and there are probably constitutional reasons for this.
