What matters is forcing your beliefs on other people. In my view, the most outrageous manifestation of this is the indoctrination of children, most outrageous because it is the common practice for major organised religion so to do. Religious people are fond of reminding atheists that we can't prove there's no God (even though we don't need reminding), forgetting that they can't prove that there is one. Yet they act with cast-iron certainty in the passing-on of their highly questionable dogma to their children. I can respect any individual for holding any beliefs they like but I can't respect anyone who passes it on, or who defends this abominable practice, to impressionable people who are strongly discouraged from questioning.
