I'm not sure if religiosity is the right word to use here, but I can't really think of another term to describe it. Basically, over the past few months, I've began to notice that Christians (of any denomination) tend to be the most "religious" and "adamant" about the fact that their religion is right and that all other religions are wrong.
From talking to Muslims, Jews, Hindus, etc. (or even reading things that they have written, or speeches I've attended) it seems that most world religions tend to be fairly open about the fact that their religion is one of many, and that other religions are just as credible as theirs. For the most part, however, Christians tend to hold an opposing view to that. The large majority of Christians that I interact with in some way (through dialog, reading, listening, etc.) tend to be very adamant about Christianity being the "one true religion" and the others as being heresies or just simply falsifications of their true religion.
Now, I realize that there are definitely some exceptions that some may have to this, including:
1. I live in America, where most people are Christians (at least nominally), so there's a greater likelihood that I will encounter people of this persuasion.
2. I'm in a college setting usually, where younger people tend to be more idealistic, and thus share their beliefs in a more "hardcore way"
3. I live in an extremely conservative area, so the population is just naturally going to be a bit more traditional
However, I still think that there are other reasons as to why Christians tend to be more "hostile" (using that word as kindly as possible) towards other religions. The problem is, I'm not sure why. Sure, the Bible says that Jesus is the "way" and stuff, but virtually every religion makes truth claims like that.
So I guess I am making this topic to ask for some reasons as to why some (if not many) Christians are very adamant about the fact that their religion is the "one true religion".
Also, if you don't feel that you have encountered this, please also speak up. I honestly feel a distinction though (as far as tone, attitude, etc.)
Cheers
