Now that's a hard question to answer! Some Jews will tell you that it does, because by not keeping kosher you are ignoring quite a few of the 613 Mitzvot (commandments) given to us by G-d in the Torah, commandments that every Jew is expected to follow.
Having said that, Jews are traditionally quite a liberal people - at least in our opinions on others, even if many of us choose to live quite conservative lives ourselves. For example, I keep strictly kosher (which admittedly isn't too difficult since I'm also vegan) but I most certainly don't think that anybody who does not is a bad Jew. The 613 Mitzvot are broadly divided into the mishpatim - those for which a reason is given - and the chukim - those for which no reason is given, and the laws regarding food are in the second group. As such, we simply do not why these foods are forbidden to us - it could be to show our faith in G-d's word, it could be for some trifling, unimportant reason, it could be due to some reason of G-d's which is beyond our comprehension. We just don't know, and for that reason many people might well argue that as independent human beings we are all allowed a little bit of leeway to decide for ourselves here. So long as you carry out the most important miztvot, such as chesed ("loving kindness," charity), respect for your parents, not doing to others that which you would not want done to yourself then I'm sure I'm not the only person who would still think of you as a good Jew.
It makes you a less-religious Jew.
The Torah forbids Jews to eat pork (Deuteronomy ch.14). Doing so (for a Jew) is a violation of God's command.See also the Related Links.Link: The Jewish laws of keeping kosherLink: Why do some Jews not keep kosher?
No. A Jew is just a person who practices the religion of Judiaism. "Bad" is a relative term. Who decides what's "bad?"
because it will make you fat
They make you poop.
No.
OpinionIt is neither good nor bad for a Jew to become a Christian; it is simply a matter of personal choice. For it to be considered bad for a Jew to become a Christian, it should also be considered bad for a Christian to become a Jew or, for that matter, a Muslim. There is no reason to consider inter-faith conversions bad.
Yes, it can.
Because you make a mess!
The Holocaust was the attempted genocide of European Jews, it was bad to be a Jew in the Holocaust because you would be murdered.
Eating noodles can make you get a lot of carbs, and carbs make you gain weight.
BAD! and abused!
Jews eat kosher by ensuring all their food complies with the laws of Kashrut. The easiest way is to ensure that all the food they buy is under Rabbinical Supervision and that they don't mix meat products and milk products. Kosher foods: * Animals needs split hooves and to chew their cud and be slaughtered ritually * Maritime animals (fish) needs fins and scales * Meat (and fowl) are not cooked not served nor eaten with milk products (milk, cheese, etc.) * Separate dishes are used for meat and milk
