"There are biblical jews who will carry a handkerchief, but will not do labor on the Sabbath. They also do not accept that the proscription against "seething a kid in its mother's milk" forbids them having a cheeseburger."

Cheeseburger I can understand. But forbidding chicken parmesan seems a little strange, since chickens are (last I checked) not mammals.

There are some schools, and in fact the Talmud indicates that some of the Sages would agree with you. As it says on the label, "Consult your Rabbi".

This one is complex.
To my knowledge (I am sure that Yehuda or Alouette could correct me) birds and fish are not classified the same way that cattle or sheep are. There is no rule against having chicken with milk. However, many Rabbis opoosed eating dairy with fowl as it confused people.

Karaites who do not adhere to the Oral Law are rather literal. The commandment in the Torah is to not boil a kid (young goat) in its mother's milk. A Karaite could eat a hamburger so long as the cheese did not come from the mother cow, but would eat dove parmesian not chicken. However Karaites do not eat chicken as it is a species not mentioned in the Torah. Rabbinate Jews eat all fowl.
