Speech as in ideas is very very deadly.   Totalitarian regimes put into place by speech have killed millions.  Democrat policies kill thousands every year in the US (using guns as one of the tools).   It's free speech that gets us politicians that promise freebies for all while providing nothing but misery for those they claim to help.   Guns are merely one of the tools.  And no you can't regulate either without drastically infringing on people's freedom.
