Hm, you may be right depending on the situation. But deliberately hurting someone else's feelings just because you disagree with them isn't necessarily a good idea either. Especially since it's entirely possible to talk about these kinds of things without hurting each other.
And while I do agree that everyone should be open to criticism, it's more difficult when it comes to "truth". Because I'm pretty sure nobody thinks what they believe is a lie - everyone is convinced that what they believe is the truth. So demanding others should be able to handle the truth is not as simple.
But I'm not sure if this is the right place for such a discussion anyway - especially since I already tried to address many of these issues in the game itself. ;)
Thanks for your input, though.
