1. Some animals eat each other, it does not make it less 'wrong' for humans do. Differences exist between expectations and abilities among species of life.
2. Christianity does not treat women 'second class'. Anymore than the right hand treats the left hand 'second class'. Christianity lays out how males and females work TOGETHER. That this difference is a matter of inferior or superior is a modern construct of the ego.
3. Many religions do consider sex with same sex a sin, just like sex with family. Love is love, that is not a justification for all types of sex.
4. No matter how much we push evolution, the same question exists, where did whatever we 'evolved' from, come from then? and where did THAT come from? Neither evolution or creation have an adequate and definitive 'beginning' from which everything starts.
5. IT is a shame that many push things that are nowhere in their scriptures. The Bible, for instance, mentions nothing about sex ONLY being for 'procreation'. The Bible describes sex as a pleasure to be enjoyed between husband and wife.
Ephesians 5:22-24 ESV /
Wives, submit to your own husbands, as to the Lord. For the husband is the head of the wife even as Christ is the head of the church, his body, and is himself its Savior. Now as the church submits to Christ, so also wives should submit in everything to their husbands.
1 Timothy 2:11-12
Let a woman learn quietly with all submissiveness. I do not permit a woman to teach or to exercise authority over a man; rather, she is to remain quiet.
If a man sells his daughter as a servant, she is not to go free as male servants do. Exodus 21:7
If, however the charge is true and no proof of the girl’s virginity can be found, she shall be brought to the door of her father’s house and there the men of her town shall stone her to death. Deuteronomy 22:20-21.
Behold now, I have two daughters which have not known man; let me, I pray you, bring them out unto you, and do ye to them as is good in your eyes: only unto these men do nothing; for therefore came they under the shadow of my roof. Genesis 19:8
The bible thinks women are 2nd class.
I would first point out the bible does not 'think' any more than our history books do. It is a collection of books of what people did and thought.
secondly, deuteronomy and Exodus were regarding a specific people in the OLD TESTAMENT who were held to the highest standards for being chosen.
In that culture, there were PRE CHRIST and largely cultural values, instead of CHRISTIAN ONES.
When we were saved by Christ, the NEW TESTAMENT, then laid out the innate equality of us all in our relations with God, and it also laid out the blueprint of how we are best able to live serving him and according to His design.
I do not feel second class. Christ never gave an example that women should be 'second class'. In fact, I would say 'class' is also a more modern concept created by human ego and revolving around worldly statuses like finance or authority.
