Victor,
"If I started a forum with a bunch of atheists and started in with comments such as "it's fine if they want to be christian, but I don't want to see it" or "it's wrong for them to be christian, my logic and science says so", then I would have a level of responsibility when a less than intelligent individual reads the entire forum and forms the misguided idea in their head that a large percentage of people would be happier without any christians on this world. Again, this is not a bad or a good thing, but one should be willing to accept the responsibility when it happens."
Actually, atheists don't need to have a forum. Their entire philosophy suggests that all Christians are idiots. The fact that atheists exist at all could therefore give sufficient justification to those that would want to hurt Christians. But to humor you, if you did have such a forum and someone beat up a Christian, I wouldn't blame you. I would blame the bully himself.
"The prevailing zeitgeist will always have an influence on what individuals along that spectrum think is appropriate to do. People are idiots. If sufficient people vocalize their "disagreement with it, but not sufficient enough to personally do damage" then people who want to do damage will think it will gain them favor with the other group."
People are idiots. I agree with that.
But you continue to confuse the long term effect of "hate speech" with the simple negative discussions being tossed around on these forums. The two are not synonymous and it's rather tiresome to continuously hear how simple jokes and honest opinions can drive people to hate.
When we were kids, most of us probably lived by the "sticks and stones" mentality.
Now we learn that "words can hurt" and it's taken in a literal sense.
It's all related to political correctness and it's a shame that otherwise intelligent people buy into it 110%.
When it become personal, it sucks. We all know that.
But all the more reason to teach kids and all the Idiots out there to roll with it, rather than assigning blame.
