What is the reason so many people hate Jews throughout history and currently?

They are perpetual outsiders. They stick to their own and they will only help their own. Jewish-owned business tend to hire only Jews and will work together to push out non-Jewish ones. Jews also tend to name buildings and things after themselves and call their organizations Jewish this or Jewish that. There's also the powerful Jewish lobby present in every country. They will lobby to protect Israel even though they are all living in another host country and have been living there for however long. They will call anyone who criticizes Israel anti-semite and give the impression that they care more about Israel than the country they're living in. Their religion is what creates this sort of attitude where they will only look out for their own. All of this breeds resentment.
