What are some good global religion websites where I can find articles with arguments?

For a particular religion, against a particular religion, or against religion in general?

I can give you all.

Some of my favourites from the atheist camp are:

The Skeptic’s Annotated Bible
Why Won’t God Heal Amputees?
God Is Imaginary
On the comical side: Hundreds of Proofs for God’s Existence
More serious: Why Atheism?

Your premise is missing the basic issue of religions. Religion is based on faith, not on fact, belief, not arguments.

By the way, the best website for a justification is probably Scientology.

@Seek_Kolinahr Thanks for all those terrific links!

The go to book since the 1970’s (I’m sure you can google excerpts and find commentary) is Evidence That Demands a Verdict by Josh McDowell. You can also google Christian Apologenics if you are looking for arguments.
As a Christian I hate this stuff. I used to be emersed in it but as I have grown I have realized that it is not my job as a Christian to change people. It’s my job to try and reflect Jesus, not cram him down people’s throats. If you want to hear their arguments though, this is where you’ll find them, just don’t associate me with those kinds of Christians please.

Do a search for William Craig. He has done a number of debates defending Christianity. Atheists can test their logic against his arguments.

This is perhaps the best one, if what you’re looking for is what many different religions are about, and different religions get their say on there. Also www.angelfire.com has many decent criticisms of each religion too, but you’ll have to dig around on that site to find them. Wordpress is another viable option too. These sites look at religious material through a more open minded theistic perspective rather than an atheistic one.
