The internet is known for bullies and trolls. Any idea or thought put out online will draw fire and criticism. Anyone who expresses their point of view will likely be attacked. I am not opposed to the system. It is what it is.
That being said, the online atheist group is the nicest set of people I have run across! I know I have only met a small segment of the non-believing crowd. I am comparing atheists to interactions with various religious groups, political groups, demographic groups, and geological groupings of people I have dealt with personally.
I think that speaks volumes about the concept that morality must be associated with any particular deity concept.
