Scientists do what you say they would not do every day. They build cases to support their theories and sell them as absolute truth for money, prestige, power, etc. that are regularly proven wrong or distorted and have been for centuries. Keep trying with that one because you could not be more wrong with that statement.
What exactly is moral to an atheist? If there is no God, why do you choose to follow morals created by followers of a God? Those morals did not exist until created by (fill in the blank). Why would you get mad about any subject or conversations by "theists" over morals at all? Make up your own. Live like you are in charge of your existence and go your own way. Just follow the laws no matter what they are and stay out of jail. Entire nations and cultures have disappeared throughout history believing they can do whatever they decide is moral. So knock yourself out.
It is intellectually insulting to sell evolutionary process as the source of community and empathy. If it existed it would be tied to DNA, genomes, cells, proteins, mutations, etc. There is no empathy in that arrangement. It is calculating and defined. I say 'if' because adaptation to environment by species have nothing in common with evolution of species. Evolution is dreamland fantasy. Adaptation to environment by species is real. The very process that brought the theory is one of survival of the fittest. But I did notice that you did not include love in its many forms, mercy, hope, sacrifice, etc. Is that because they are intangible and not easy to identify in the evolutionary process?
