Everyone has their own definition of what is Jewish. For the non-orthodox, it is a social club; all are welcome, no requirements. However when non-Jews are given Jewish identity papers, that is a stumbling block for Jews that can end up marrying these gentiles having thought they were Jewish. People need to know whether a person is halachically Jewish or not. People have a right to know. Diguising a non-Jew as Jewish is a crime of impersonation. It is deceit. Feel free to consider your "converts" Jewish in your hearts, but do not issue them Jewish identity papers - that's simply criminal.
