Mocking or scorning is a serious issue with God. Here are some Scripture verses to illustrate what God thinks about it.
Scripture Verses about Mocking or Scorning
Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful. But his delight is in the law of the LORD; and in his law doth he meditate day and night.

New Testament Passages...
Knowing this first, that there shall come in the last days scoffers, walking after their own lusts, And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation. (2 Peter 3:3-4)
But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ; How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts. These be they who separate themselves, sensual, having not the Spirit. (Jude 17-19)
The fact is that people will mock or scoff at what we as Christians believe. I see it often in blogs and other places. Remember that if they do not turn, they will get their comeuppance, either in this life or the next.
