*Disclaimer - all things stated are most likely an opinion, and if they are fact and you don't realize that but still want to [argue/debate - I see this as a tool for learning, not something hostile, hopefully we can overcome such petty things if we disagree and reach constructive conclusions, even if its in agreeing we disagree, just respect enough to state your point, answer/justify/point out logical fallacies, and perhaps reconstruct our perspectives if they were portrayed incorrectly. I don't mind being wrong or being told I'm wrong, it simply makes me think of better ways to be right in the future]
The point of studying any philosophy...well I'll break this down into the most basic reductionist views. Occams razor is comin for ya'll
The point is a subjective one, and it pretty much always will be if we are speaking about individuals. What it means to you, how it affects your thoughts and views about life.
With that being said, even if a philosophy is completely against everything you believe in or you disagree with a large portion of its foundation, if it is able to hold itself up well enough to become a philosophy which is studied, then chances are that its structure alone is [or may be] worth giving a look at. Whether you learn positive things that you agree with and expand you're thought processes and perspectives or you sit and see how the processes of thought that many others follow or used to follow work and are at first completely baffled how someone could swallow so much horse shit, you are learning. By understanding the structures and scaffolding of a philosophy, the basic principles and ways in which it applies to various facets of life, you allow yourself both to possibly understand more about how/why others believe some outrageous pseudo-scientific fanatical things, and you can compare and contrast you're own beliefs and thoughts to the others and perhaps see the points in theirs that you view as weak and then question your own as well, and the same goes for the parts of others beliefs that are backed solely by subjectivism and faulty logic, if you can recognize it within another, you can become a better self editor as well. By understanding the way others perceive the world, even if its an extreme view that you disagree with, if you take the time to try to recognize the foundation for these thoughts perhaps you will have both the ability to communicate better and help the other person understand where you stand without attacking their positions, or lessen your intolerance for those you disagree with (lest they impose their values upon you and criticize yours, which in the end they only offend themselves by showing they can't appreciate their own values enough to have them as their own, they are offended that others don't agree, they let someone else evoke feelings within them and control them enough to become an offender of their own dignity by doing so

If you disagree with something or have strong convictions in your own beliefs, it doesn't seem like it would hurt to know thy "enemy". If there are people or philosophies that criticize or contradict what you think, you can study them and find either where they lose objectivity and have flaws, see where they point out weaknesses in your beliefs and perhaps revise or at least question your own beliefs enough to either re affirm them, realize there are stronger or different ways to still keep that belief that are not subject to the enemies attacks, or perhaps change some aspects of what you think, adapt, evolve.
The point is to learn
