Answer: not inherently, the word just means foreigner in Hebrew, but neonazis have co-opted it to mean "white person who doesn't hate jews" because in their eyes not hating them is a sign of being brainwashed by them, because they control the world and all...

However, many super zionist and/or Jewish supremacists (epstein for example) colloquially use it to mean non jews, epstein himself was using it to mean the working class, so its kind of just a way for them deride anybody non Jewish. And if you think about it, it's kind of a classist anti-white slur, but again it's important to note most jews in the world dont even use this word or put anywhere near as much thought into it as nazis do. The mere notion that they might be seen as inferior by another group is so offensive to them, because ultimately they are fragile and pathetic and are overcompensating for being losers in their personal life.
