Tell those anti-semites that
1) Less Jews (percentage) than the population at large use governmental welfare services
2) Jews pay more (percentage) taxes than the population at large
Thus Jews who legally qualify for medicaid, food stamps, etc. are fully entitled and expected to take full advantage.
Tell them to start worrying about the far larger numbers (hard numbers and percentage wise) of African Americans, Hispanics, and other ethnic groups that put themselves in a situation or lazy around to require services.
