"Satan is not going to go after fake gods?"
Well, plenty of people who aren't Christians are persecuted for their beliefs and have been for centuries, if not longer
"Which belief is attacked more than any other?"
I actually don't know, but it's certainly not THE MOST POPULAR RELIGION IN THE ENTIRE WORLD (yes, Christianity is the most popular religion in the entire world), and it does much more attacking of other religions than being attacked, which means, by your logic, that it is Satan's religion (I don't actually believe this, it's simply a natural extension of your logic)
"Which belief do some countries kill you or put you in jail for believing?"
Actually, there are many, many beliefs that countries will kill you or put you in jail for believing. Non-Christians being the ones executing Christians or putting them in jail is a relatively new development, whereas Christians have been torturing, executing, and imprisoning atheists, Muslims, Jews, Wiccans, and pretty much everyone else who wasn't a Christian pretty much ever since Constantine. Did you know that, in Islam, Christians aren't Infidels, but are instead considered "people of the book", and are to be respected? It wasn't until Wahhabism was developed that Muslims persecuting Christians for their religious beliefs really became a huge thing.
Sorry to break your comfortable conspiracy theorist delusion, but while Christians have been and are persecuted in many third-world countries, they aren't "persecuted" in America just because people are finally brave enough to speak out against them, and they've also, historically, been the persecutors more often than the persecuted (and are still persecuting people to this day).
