Don't even acknowledge them. They deserve nothing. If they choose to discuss our faith, that is fine. However, if they desire to mock and ridicule, then that tells me more about them than any biography. These immature psuedo-intellectuals sit in their mom's basement and troll the internet for easy targets to boost their stunted egos. Picking on individuals with conviction is an effective means of coping with a poor self image and feelings of worthlessness from a lifetime platonic and superficial relationships and living. Christians are among the most desirable targets, because our words and beliefs cut deep into their under-developed consciences. Let them laugh and scoff. In fact, I encourage it. That's the last good feeling they'll have for a good 7 years pretty soon. Let them laugh one more good time, really have a riot. Perhaps these memories will comfort them in their abject terror when they are faced with judgement from a Holy God. Maranatha.
