Can you be a proper Jew if you dont follow laws of Judaism?

Other Jews disagree to this; they believe that you don't have to obey all the laws of Judaism. Reform Judaism is one type, it is the most liberal expression of modern Judaism.

In the 19th century Reform Jews took a huge change in their religion, discontinuation of prayers for a return to Palestine, prayers and sermons recited in German instead of Hebrew, the addition of organ music to the synagogue service, and a lack of observance of the dietary laws. Some Reform rabbis advocated the abolition of circumcision and the Reform congregation in Berlin shifted the Sabbath to Sundays to be more like their Christian neighbours. Modern Reform Judaism, however, has restored some aspects that their ancestors abandoned including the practice of religious rituals, prayers recited in Hebrew, the Sabbath on the Saturday and religious festivals. But still most Reform Jews consider the dietary laws to be an outdated ritual and ignore them completely.

Conservative Judaism is a moderate sect that seeks to avoid the extremes of Orthodox and Reform Judaism. Conservative Jews wish to conserve the traditional elements of Judaism while also allowing for reasonable modernization and rabbinical development.

Conservative Jews observe the Sabbath and dietary laws, although some modifications have been made to the latter. As in Reform Judaism, women may be rabbis. In 1985, the first woman rabbi was ordained in a Conservative synagogue.
