what's the difference between a bank and a jew ? a bank will lend you money .
It sounds like you are just making stereotypes, and putting things together that don't belong together. Why would you say something like that?
Jews are cheap and... well greedy, because they can afford to be
Statements like this just perpetuate stereotypes about Jewish people being stingy that have no basis in actual fact. People are individuals and choose to either spend freely or to be miserly, and this choice has nothing to do with their religion.
You are the typical PC SJW. You just can't joke about anything. You should try watching some Roosh vid.
You can make jokes but they shouldn't be targeting any faith. Use your sense of humor to make non offensive jokes. It's not right to paint jewish people as stingy.
