Don’t be disgusted.

Some rishonim understood from the simplicity of the Talmud that "do not detest" is a prohibition from the Torah. Other rishonim wrote that it was only a rabbinical decree, and the sermon in the Talmud is a reference from the Bible. Maimonides wrote that although the prohibition is from the Torah, it is not included with the other prohibitions in the Torah for which a punishment of flogging is prescribed, because it does not fit the simplicity of the written text.
