Opinions are not crimes. They are thoughts. Once government attempts to turn opinions into crimes, it opens the door for any thought that they don’t like to become a crime.
The best way to counter distasteful opinions is with free speech, so that the truth can shine a light on them.
Opinions can change. Opinions are always changing. But allow the idea of “hate speech” and government can make it a crime anytime you open your mouth in opposition to them.
