Charlie,
Tikun olam as referred to in maseches gittin has nothing at all to do with the krumkeiten of the reform. And much more to do with what it says in Alenu and preserving yidden. Not preserving manatees, nor tearing down jewish companies. Nothing of the sort that the reform and others who want nothing to do with the Torah would describe as “Tikun Olam”.
In fact the items included in the mishna is in direct opposition of how the Reforma and their ilk define tikun olom.
