I'll briefly comment on something I occasionally observe. You have professing believers who lose their faith due to personal tragedy. Something terrible that happened to them or someone they love.
But they don't just lose their faith. They respond by conducting a vendetta against Christianity. They may visit Christian blogs and unload on the blogger or other Christian commenters. They raise stock objections of the village atheist variety.
When Christians respond, they complain about how heartless Christians are. Christians have no empathy for the ordeal which the apostate or his loved one went through. Indeed, this just confirms why they gave up on Christianity in the first place.
At this point I'd make a couple of observations:
i) Apostates like this don't have a monopoly on personal tragedy. For all they know, the Christians whom the apostate is angrily denouncing for failing to understand what it's like has been through the same ordeal, or worse.
ii) When apostates act this way, it creates an unnecessary dilemma for Christians. On the one hand, we'd like to be sympathetic to your situation. We'd like to be good listeners.
On the other hand, you make that very difficult when you use your suffering (or the suffering of a loved one) as a bullet proof shield to hide behind while you fire away at Christianity.
Frankly, that's inappropriate. You don't have a right to force us into silence by exploiting your tragedy to attack the Christian faith. That's very cynical and manipulative.
It's up to you how you wish to be treated. We'd rather be compassionate. But if you take advantage of your tragedy to avenge the Christian faith, then you've left us with lesser options.
