The racial slur's origin is fundamentally irrelevant. Uncle Tom, for example, refers to a segment within the "race" that are seen as traitors to it, and therefore, is in no way problematic. Like n., this word is anti-Jewish in general, and is not meant to offend a segment, but every single Jew.
You may believe it should be used in such a manner as to refer to weak traitors. This is not the accepted use, the one every Hans with tattooed heads has heard of refers to Jews in general, and it is a way for them to group Jews as a whole and call them this particular thing, not a way to insult one or two, or a group in the tribe.
If you want to make a word to describe beasts like Shimon Peres (YS"V) and George Soros (YS"V), I will support it. To use a word that groups Jews as a whole, and makes us look like scummy hoodrats calling each other slave is only detrimental, accomplishes nothing positive for us, is unnecessary vulgarity, and if it causes one person to turn from JTF, was it worth it?
Keep it up, and you'll disappoint all the neo nazis that come here who thought we were antisemites, and all the Jews that come here and think we support am Yisrael.
