An "activist" is someone who "use direct, often confrontational action, such as a demonstration or strike, in opposition to or support of a cause.". Whereas these people are not activists, they merely live according to their values.

You are right. However, that doesn't stop others from calling them activists. If you are on the so called "far right," then merely living out your values seem like activism to those who are opposed to you.
