I helped write, along with other comrades, the following “Open Letter to Comrades in the ISO [International Socialist Organization]” in the Fall of 2013. The letter was posted to a temporary website called Socialist Outpost. While I, and other signers, may no longer agree with everything in this document, I think this letter has some value. As it is no longer online, I am reposting it here. The core of our argument, to search out greater collaboration with other “sane” revolutionary socialists remains valid. I honestly believe had we pursued this course, and had the former leaders of the ISO not secretly covered up a rape and sexual assault, we may have won more of the current generation of socialists for revolutionary Marxism earlier on. - Adam Turl.
