Anticipation Guided Response

It's possible to believe in love at first sight
I disagree, If you believed in love at first sight then you would be judging a book by its cover. In other words that would mean that looks is the only thing that matters in love, whereas character, or having common interests is more important. Unless you're someone for whom looks is the most important thing only then can you fall in love at first sight.

Two strangers stuck on an island together could learn to love each other
I agree. They would get to know each other gradually through sharing experiences. They may end up having to work together to survive on that island and might eventually fall in love after getting to know each other. Spending time with someone will help you get to know each other and appreciate each other's good points because you will be able to get to know them deeply rather than superficially as you might if you were not having to spend every minute of the day together.

It is a good thing to sacrifice your happiness for other people
I agree. Someone might need something more than you do and it might not be such a big loss for you if you gave that thing up. Besides at the end of the day, helping another person will make you feel good yourself because it is always better to give than to receive.

Women in your society are free citizens
I agree. Women in our society have the same rights as men do. Women can do anything men can do. Maybe even better! However women should get equal pay for equal work. And because women are financially independent nowadays, they are free to do exactly as they please. Unfortunately many women in our society find themselves in a position where they have to do everything - they go to work and they look after the house and kids. Husbands don't do anything but they will all get the boot when my generation grows up because we wont stand for that.
