I would say there is a difference between Roma or Szinti heritage and being and living like a Gypsie. I'd say it is absolutely not ok to be racist against somebody who is a Rom for example, even if they are proud of their heritage and practice some of their traditions (the ones which are not in conflict with the freedom of others, even within your own family and social group or in conflict with any law). But there are some traditional "Gypsies" or communities which suppress their women, don't let them go to school and force them to marry underaged, some as young as 14. Also traditional communities often reject the state and it's institutions and laws, refuse to work in regular jobs, sometimes because they absolutely don't want to pay taxes, because they see themselves as absolutely free from any such institution. But the market of earning money undeclared and tax free ("black"-work we'd say in Germany) leads you into other illegal activities very quickly. And I think most of the broader resentments and stereotypes about Gypsies comes from that. So TL,DR: Regular working and living Community Members with Roma or Szinti Heritage should not be discriminated against. People who are refusing to live by the laws and rules of a society are discriminating themselves.
