Actually that is not true, as the issue of preserving human life, ranks above that of keeping kosher. It is better to eat food that is not kosher, than to starve. As to whether such things as pig, should even be called food, seems debatable depending on who you talk to. If that interpretation is correct, then failing to keep to kosher dietary guidelines, is likely not a capital offense. However, murder would be. See Genesis 9:6.
There are variations of kosher. Many Messianic congregations are only biblically kosher, but not rabbinically kosher. That means, they follow what the Bible says, but do not agree with certain rabbinic interpretations. Thus, cheese with beef is allowed. There is a verse in the Bible that says not to seethe a calf in its mother's milk, which sounds like something very cruel to do. Well I see no relationship to that, and a cheeseburger, as the cheese probably did not even come from the same farm as the beef. Some Jews are very strict about kosher, and can not eat dairy and meat products in the same meal, or do not even use the same refrigerator or stove for both, requiring special kitchens with diary and meat sections being kept separate, even separate baking dishes, but I see nothing in the Bible requiring any of that.
You should also keep in mind, that both Christianity and Judaism, do not do forced conversions, as Islam attempts to. Both believe that you should convert by choice, and not by force. Although many matters of morality obviously must include both believers and non-believers, what about the matter of kosher, requires this? Many matters, seem to be answerable more to God, than to the church or synagogue, and definitely the government has not much to say (no jurisdiction) about many things.
Homo-phobic is an invalid word, as it implies things that make no sense. A better word, that you may have noticed me, saying, is population-phobic. People do not "decide" to be highly populous, they just are. As our ancestors believed, population is what it is. There are problems with trying to cite individual people for collective sins, as I as an individual, can not control what the collective does. What is this I hear about London trying to charge people "congestion" fees of motorists? One person does not cause traffic congestion, so why fault individuals for problems caused by poor road design or by corrupt politicians? Also, I can not fault India for having such a huge population, as huge population is not a sin, nor does having 10 children cause the population to be huge.
Fine, you want to select a different passage from the Old Testament to hold up as a comparison to the homosexuality issue?
How about murdering non-virgin brides on their wedding night?
Or killing disobedient children?
Or expecting women to marry their rapists?
Why limit it to the Old Testament? Do you think slaves should be obedient to their masters? Do you think they should be more obedient if their masters are Christian? What about killing non-believers? The New Testament has fewer such passages, but it does have them.
What about things in the Bible that are not morally horrifying, but merely wrong? Do you think that you can affect the patterns on the fur of livestock offspring by changing what the parents look at while they mate? Do you believe the firmament is a physical barrier that separates the sky from the waters above it?
The point I am trying to make is that even literalists are forced to pick and choose which passages of the Bible they will follow and interpret literally. Thus, even if the original poster is from a literalist tradition, I don't think he should worry about the theological implications of his homosexuality too much. The more relevant question is how his local Christian community is likely to treat him because of his homosexuality.
