I may be too picky here, but don't you think that the tag "jesus" should be starting with a capital letter?
No not really a big deal in my opinion. Tags are traditionally always lower case, not just on this site but on a good many other sites as well. It would get very messy if they allowed upper case at all and doing it just for a couple proper names doesn't make much sense. I think it's better to just leave tags as all lower case.
On the other hand, in the titles and bodies of questions it should definitely be capitalized.
It absolutely should be capitalized. Christians should not be the least bit afraid of standing out, much less in the case of having the only capitalized tag in all of SE. It is, after all, the name of Jesus. There is none other name under heaven, given among men, whereby we must be saved. To leave it lower case is to profane it to some extent.
