I think the law (generally in western countries) gives you some liberty to express how you disagree with it.

The issue with having as you mention guidelines in line with the law, is that it prevents people discussing it. Which is an absolute necessity for lively democracies.

You're going to tell me that you can discuss the law without breaking it. But that's a very debatable point. Generally the law moves because of pressions from interest groups that would be beneficiary from a change. So banning them would in effect ban the most vocal proponents of changes and those that really understand the fine details and issues and that can meaningfully make the debate progress.
