Denying it or not liking it doesn't mean it isn't real.
Hell was originally created for Satan and his angels. In the future it will contain those who join Satan in rejecting God. If you reject God's provision for the forgiveness of your sins, then you will join the Devil who rejected God from the beginning. Is that what you want?
Could you believe in a God who would become a human, suffer at the hands of humans, and be killed by them, all so that His death could be the payment for their sins? That is extremely loving. God is saving people who deserve to go to Hell, and we all deserve that. Remember that the same God that sends people to Hell also died for them. If they reject what God has provided, then what is God left to do? He would have to judge them.
Whether you believe in something or not does not change the fact of its existence. Jesus spoke often of Hell (Matt. 25:41-46, Mark 9:47-48, Luke 16:19-31) and warned us so we would not go there. Would you say Jesus didn't know what He was talking about?
Are you implying that it is unjust for God to send people to Hell? If so, then you accuse God of injustice. Sin is wrong, and it must be punished. What would you have God do to those who oppose Him and do evil? Do you want Him to ignore that which is wrong? Do you want Him to turn His head and not be holy and righteous?
