Syag…so claiming that most reform and conservative jews are not newish and therefore we don’t really care what they do/say (which is the upshot of besalel’s post) is calm, respectful and not mincing words? I don’t understand you very well. If you want people to write dispassionate, academic posts about the difference between orthodoxy and its deviants…rachmana liba bai. If you want criticism to be with understanding and sensitivity – ell i agree that’s what works but there’s a time and place for “hakeh es shinov” too, and i think an anonymous online forum is a good place for it.
The claim is also untrue. Many jews in the reform and conservative movement are not halachikally Jewish, but the majority are. It will be another few decades before that changes. That’s especially true in conservative circles, where there are established JTS/solomon shechter families that are, lehavdil, similar to “chaim Berlin families”. For many years the aforementioned groups have expressed animosity towards Orthodoxy, claiming that because we regard their beliefs as non-jewish, that we also do not consider them jews either. Now they may not have the din of a yisroel regarding bishul, etc…but they are Jewish and it discourages newcomers to portray anything to the contrary.
Also, it should bother us if goyim masquerade as jews either way, because it’s a massive chilul Hashem.
