Looks like some jewish emigrant from East Europe with bad knowledge of English and high conceit wrote that template. In slovenian languages there is word "отказник" (otkaznik) from the word "отказ" that mean "refusal". "nik" suffix is used to create a description of person who connected with object described by root part of word. Like "печник", "лесник", "дворник", etc. All slovenian languages have that thing. So, that emigrant just combined "refuse" and slovenic suffix "nik" getting "refusenik".
