Law 2

I think they are limited but it also depends on how the individual interprets the law, and that's if the law has more than one meaning.  Most, if not all the laws formed by the governemnt and in the Constitiution are stated clearly.  However there are some that are controversal.  For example, burning the flag of United States of America.  If a non-American citizen burned a flag of United States of American would that person be considered a terriost, and if an American citizen burned the flag, wouldn't the person be considered a terroist as well? Also, we humans can abide by the laws that govern over us or we can go against them.  We all know what is right and wrong.  But we also follow our own morals.  Our morals also govern for what we stand and believe for.  Christians follow the Bible and obey God and other people follow their country's laws and follow their god too.  But there are also times when Christians have to go against the law in order to do God's will.  For example in the Bible, Daniel gets thrown in the lion's den because he prayed to God when it was outlawed.  Missionaries go against other countries laws because they are sent to spread the word.
Therefore there are two sets of laws: Man's Law and God's Law.  God wants His followers to follow the law that rule over them and to follow His rules or guidelines.  If the government tells them to do something that is against the Bible or against their morals, then what?  I think that Christians would not follow the orders and obey God's.  Man's laws are flawed but God's laws are holy, sacred, and divine.  In other words, yes, laws are limited to our interpretation.  We can choose to follow or go agasint the laws.

Law

Government is not the ultimate authority because God is the Judge and the Authority.  God is the first being to even create laws.  In the Old Testament He created the first law (in my opinion) of not eating from the tree of life, soon the Ten Commandments followed, other laws in Leviticus and so on.  We should respect and follow the laws formed by the governemnt, but God's as well.  If the government goes against the law or asks you to go against it, than the government itself is can't be the ultimate law because the law can be easily distorted and changed.  God's laws however do not change and stay the same.  What's the differnece between a distorted law and God's law?  You will never know the meaning of a distorted law, but if it God's law, you will know the precise meaning.  A person can add or change a distorted law, but God's law stays the same and if a person tries to add or change God's law, that would be blasemphy.

Feminism

Christians should respond to feminsim not in a degrading or hateful way, but in some way make it into a friendly converstaion.  They or me, should say that feminism takes the word femine out of females in away.  Feminists want to be treated the same way as men, but I should ask what there definition of being treated the same way?  I understand that women who work the same jobs as men should be paid the same amount of money, but the physical conditions should stay the same and women should work the same hours and no short cuts.  If feminists want to be treated equal as men, they need to accept the physical conditions.  If women want to join the military, than they would need to go through the same training as men, or if they want to be a doctor, they need to go through the same training as men.  Even though God created men and women differntly, women should still be treated equally.

Feminism within the household is different than from the Christian perspective.  If they (feminists) want to be the "man" of the house, then don't get married.  One of the causes of femisim is that women begin to sleep around because men can do it, well that doesn't make it right.  When women sleep around it causes higher rates of abortion and STDs.  From a Christian perspective, there is a reason why men are at the top of the household it is because they are meant to protect, provide, and love their families.  The men of thier households might have the final say, but usually they do not make their decision without their wife's input.

Sexist; Homophobic

I think that the claim is not completely correct.  There might be Chrisitans who are like that and misrepresent the Bible because the Bible does not discrimnet people who homosexuals.  The Bible says that it is wrong because sex and marraiage is suppose to between a man and woman which creates a sacred unity.  The Bibles says that it is wrong to be homosexual.  If a person who is homosexual or bisexual, I do not mind being friends with them, but I would not particepate in the act or encourage them to keep doing their sin.  I would try my best to point it out and show them in the Bible what a marriage is meant to be.  Song of Solomon is a very poetic and descriptive book about marriage and sex.  It talks about a man and a woman, not a woman and woman or man and man.  Also the Bible does not teach Christians to stay away from people who are homos or bi, but to love them and help them get out of their sin and live a godly life. 
If I was placed in a group of homos and bis, I would feel out of place and uncomfortable, but I would try my best to be a light.  I would engage in conversations and treat them with respect but I do not agree with their perspective of what marriage should be like.  In other words, I would stand my ground, and if they ask me what I think, I would tell them without trying to put them down or hurt their feelings.  I would pull out my Bible and show them references about marriage and sex.
