This presents two problems for me:
- I’m dealing with intense distain for my fellow human beings, which is a challenge in itself of my Christianity; and
- These are people with whom I’m going to be “socialising” and studying. If I don’t socialise with them, then I’m being intolerable. If I do socialise then I’m a traitor to my own code of ethics and a hypocrite.
What am I supposed to do? Is society becoming increasingly immoral, or am I just too conservative?
You are having difficulty solving your problem because you are looking in the wrong place. You are focusing your attention on your friends, when the root of your problem is inside.
It is almost always true that the things we hate most in other people are the things we hate the most in ourselves. We project our (often-subconscious) self-hatred onto other people.
If you are experiencing feelings of disdain for these individuals, it is likely because you have the same elements in your psyche that cause them to behave in the way you dislike, and your disdain and repression of those elements in yourself is manifesting as disdain for your fellow man.
You even acknowledged this yourself, even if you didn’t realize it. You said:
I might as well join them if nobody’s going to judge me.
If you were truly free of the sins you disdain them for, such a thought would not even occur to you, because that lifestyle would have no temptation or appeal at all. The fact that it presents a temptation means that sin is present in your mind, even if you are not aware of it, and do not (physically or consciously) indulge in it.
It is good that you are, for practical purposes, forced to interact with these people, because otherwise you may have remained blissfully unaware of the presence of this sin within your mind. Attempting to avoid them is simply running away from your problem.
It is also good that you were able to recognize that something was disordered about your disdain for them, and that something must be done to remedy that affliction. Many people would simply feel that disdain without questioning or examining it.
Now, to address the disdain, you must eliminate it at its source, which is in you. Do not waste any more time or energy focusing your attention on those people towards whom you feel the disdain. They are merely a distraction from the true source of your problems.
Come to a conscious understanding of the sin as it exists in you. Eliminate even the temptation for that sin from your own mind. Recognize that if you have that sin inside you (which you do), then you should be merciful to those who also have it inside of them, for as the Lord tells us, “Judge not, lest ye be judged” and “The measure that you measure with shall be measured unto you” (Matthew 7:1-2).
When you eliminate these causes of the disdain, the disdain will go away. But as long as the causes remain, the effect will continue to manifest in your life, whether it be with these people or others you may encounter along the way.
