Free speech is an inherent right to us in America, this didn't occur in America. This Canadian, where their citizens also
do not enjoy free speech traveled to Germany, where she knew that there were laws on their books about Holocaust denial and proceeded to break those laws. It's really simple don't break laws in foreign counties you visit if you don't wish to be penalized.
Would you advocate for some foreign national who violated American laws while visiting just because they believed differently? Muslims with multiple wives? Honor killings? Genital mutilation?

Free speech is an inherent right. Period. Just because Germany doesn't recognize that right doesn't make it any less of a right. Freedom of speech is given to us by God, and should be defended everywhere, regardless of location.
Having multiple wives is not a God-given, inherent right. Honor killing is not a God-given, inherent right. Genital mutilation is not a God-given, inherent right.
