In the United States, yes.
Speech which is not controversial does not need legal protection.
There are only extremely limited exceptions, such as incitement to riot, where there is a "clear and present danger" of imminent harm. I don't think that has ever been successfully applied to printed words.
If you are a racist, and you and like-minded others would like to have a parade or public rally, then you apply for a permit just like any other group. As long as you stay within the time and place restrictions on your parade permit, and are non-violent, then you can say what you like.
Here is a picture of a typical Ku Klux Klan rally:

Now, do you see the police there? They are not there to stop the rally. They are there to protect the freedom of the Klan members to peaceably assemble and to speak, including the African-American police officer that you can see in the upper left. Generally what they do is to keep the Klan demonstrators and the counter-demonstrators far enough apart that nothing happens.
What we do in the United States is to put our idiots on display, so that we can point at them and tell our children very precisely the kind of person they should not grow up to be.
I think what some people don't fully appreciate about US culture is that we have a wider variety of opinions, backgrounds, cultures, beliefs, and religious faiths represented here. If we started drawing lines around ideas that one group, or even most of us found "disgusting", and making those ideas illegal, it would cause more problems than it would solve. By and large, the normal reaction here to these sorts of hate groups is to ignore them - because what they crave the most is attention.
