If God wants us to worship him with our own free will then why does he threaten us with hell if we don't?
He doesn't - at least not in the way you are implying.
Hell is the absence of God. It's not a threat at all. It's just a statement of fact. If you don't worship God then why would he want you in his presence? More to the point if you don't worship him then why would you want to be in *his* presence?
Why is prayer ok but spell casting is not,when both amount to the same thing;asking for a higher powers help in a matter?
He is a jealous god. You shall have no others before him. That's really kinda obvious - if you couldn't see that yourself then I seriously question your intentions here as wanting to know answers but to simply be a smart-ass.
Why is Jesus called Christ,when the word Christ is a pagan term?
It's not. It's just a word that means something close to savior.
Why is Jesus called the "prince of peace" when he clearly states in Matt 10:34 and Luke 22:36 that he is not?
The only time "prince of peace" turns up in the Bible is in Isiah where it says Jesus will be called the Prince of Peace. Note it doesn't actually say that's all he'll be (in fact it lists a whole bunch of things people will call him).
Why are so many Christian holidays on the same days as Pagan holidays?
You mean Christmas? Easter is on Jewish Passover (for obvious reasons if you read the bible). They needed some time to throw a party and mid-winter sounded good I guess. May as well reuse an existing holiday.
If God is "just and merciful",why did he send bears to kill children who called Elisha "baldhead"? That seems harsh.
Kill? 2 Kings just says "mauled", but God isn't always merciful. In fact, in the OT he was somewhat temperamental and tended to smite people pretty soundly at times.
If God impregnated Mary,without her consent by the way,and Mary and God were not married,would that not be a sin? Sex before marriage. Also would that not make Jesus a bastard then?
Who said it was without her consent, and there was no "sex" involved so your question is meaningless.
What's more interesting is why do you care so much? If you're not about to become a Christian then what does it really matter to you? Seems to me like you've spent way too much time thinking about stuff that you are asserting is unimportant.
I don't personally care what you believe but when you generalize all Christians into the pet little hate you seem to have fostered, you're only becoming that which you loathe yourself and not doing anything but fulfilling the things which you complain of.
