Dear Theland, Christians can expect "flak", it's part and parcel and should be viewed as a privilege ("If they have persecuted me, they will also persecute you." John 15). But like the sensitive black guy who sees a racist around every corner, you sometimes appear to take every bit of feedback and comment as some sort of personal insult when the poster is simply making a point or asking a question. A friendly suggestion, try looking above the perceived insults and answer the posts in the same spirit as they are made. Have a look at Proverbs 26 which is very enlightening, amusing and relevant to this subject - verses 4 and 5. The first basically saying "don't rise to the bait", the second saying if you DO choose to answer (which I think you do), give him a proper answer, or you'll be held to ridicule.
All the best, Theland, have fun, and if you still insist to take the feedback from many people personally, do it as instructed in Philippians 2:14. Best wishes.
