As a Christian who believes in Thou Shalt Not Murder, and not judging others lest I be judged, I would never go up to someone and say you have to change your faith or murder. Some people people are like that, but you can't say all religious people are deadly and toxic, that just isn't true.
Theism by its very nature is psychologically toxic because you absolutely have to maintain a state of intellectual dishonesty in order to 'believe', to have your 'faith', which causes cognitive dissonance when the part of your brain which is capable of objective reasoning is exposed to information which serves to highlight the constant conflicts in what you believe and what is evidenced .
Just because you declare yourself be a "True Christian" (try looking up the No True Scotsman fallacy), who believes in only the 'good' stuff from your Holy Book, it doesn't change the fact that your Holy Book is riddle with contradictions and inaccuracies which you have to tread carefully through in order to ignore it lest it exposes your cherished beliefs to be the fallacies they are.
I don't need an invisible ominpotent sky-daddy to tell me not to murder people, I have no inclination to murder people and I tend to live by the basis of objective secular morality, that which values the autonomy of consent whereby I cannot reasonably expect my consent to be honoured if I do not value the informed consent of others.
