Others, equally respectably, choose to restrict the scope of what they eat.
The problem arises when you decide that what you don't want to eat shouldn't be eaten by others (who may or may not share your rejection) either. In totalitarian countries they do this by law, officially banning the open sale of the forbidden foodstuffs.
In at least one democratic country they do exactly the same. These days Jews celebrate the festival of Pesach, which commemorates the Jewish exodus from Egypt, which was so hasty that they didn't have time to leave their bread to leaven. That's why observant Jews don't eat leavened products (hametz, in Hebrew) on Pesach; instead they consume a kind of unleavened cracker called matzah.
So far, so good. But in 1986 a law was enacted in Israel forbidding the public display of hametz during Pesach for sale purposes in Jewish-majority areas. And as the Jerusalem Post reports,
[S]elf-appointed informers will wander the cities of Israel this holiday searching for wayward restaurateurs, bakers and other food purveyors illegally displaying leavened bread during the seven days of Pessah.
Armed with a cellphone camera and an eye - and a nose - for fresh-baked bread, each informant will relay concrete evidence of the illicit culinary activity to a group of legal activists. Police, municipal officials and the Interior Ministry will be notified of the transgression.
"The Jewish character of the State of Israel is at stake," said Nachi Eyal, chairman of the Legal Forum for the Land of Israel, whose organization is spearheading a campaign to encourage Israelis to help enforce the Hametz Law.
The article goes on to clarify that since mostly-secular Israeli Jews are hametz-lovers after all, it's very difficult to enforce this law. This may well be so, but that's not the point. The point is that being fined or not for displaying hametz during Pesach depends on the authorities' goodwill. And if you're not fined, it's not because you have a right; it's because you're tolerated.
One wonders if the State of Israel has a law forbidding the public display of food at daytime during the Islamic month of Ramadan, in which Mulsims are required to fast from dawn to sunset, in attention to the large Muslim minority that lives in the country.
Well, one doesn't actually wonder.
"Exactly the same rights as Jews," my foot.
