Not quite.

Some fascsist do this, absolutely. Others, to appear moderate, kick out minorities and "just" jail dissenters. Will they eventually start murdering people? Absolutely.

But nearly no fascist nowadays advocates for murder. They must first radicalize the people once in control via salami slicing tactics. If you look for fascists, do not look for people advocating for murder - they will be noticeable enough anyways. Look for those who can be described with the picture in this post.
