1. The Gemara explains that Rav did not really maintain that it is forbidden to eat udders.
2. The Gemara discusses whether the custom was to eat udders.
3. One who is lenient and eats udders may not do so in a city where the custom is not to eat them.
4. One who cannot control his bowel movements is exempt from the Mitzvah of Tefilin.
5. While Beis Din, when in power, may force people to perform positive commandments, there are exceptions to this rule.
A BIT MORE
1. Rav ruled that one should not eat udders in the city of Tatalfush, because he saw a woman asking her friend for a recipe for cooking meat together with milk. In order to show them how stringent this law is, he forbade the eating of udders.
2. Rav Yitzchak bar Yosef ate udders, while Rabin did not. In Sura the custom was not to eat udders, while in Pumbedisa the custom was to permit it.
3. This is because the Mishnah in Pesachim (50a) states that when a person travels to another city, he must observe both his own stringencies and the stringencies of the place he is visiting.
4. This is because wearing Tefilin requires a clean body (one may not pass gas or go to the bathroom while wearing Tefilin).
5. The Torah states explicitly regarding certain Mitzvos, such as honoring one's parents, a specific reward for keeping these Mitzvos. Accordingly, if someone does not perform one of these Mitzvos, Beis Din does not force him to perform it, but merely tells him that he clearly will not receive this reward.
