I don't believe in hurting or insulting people just for the sake of it but at the same time I cannot see why idiotic ideas or concepts cannot be pointed out. YEC is based on the ideology that in the "battle" of reality vs. Bible the former must yield every time. That IMO is sheer idiocy and such a waste of human capabilities.
I believe that YECs are good people at heart just like normal people - they have just unfortunately been brainwashed into an ideology that has zero to do with reality or rationality. Sad state of affairs...
