I'm of course an apostate and an atheist, but I don't believe most secular individuals have an interest in interfering with the personal beliefs of the religious if they merely remained personal beliefs, just as most secular individuals don't have an interest in interfering with the beliefs of those who embrace astrology or other superstition not based on reason. It's because the beliefs of the religious
exert an undue influence over mainstream society (we might still have a World Trade Center if not for religion) that objections are raised. As noted:
I've not encountered anyone who has an interest in attacking religious belief simply because they consider it irrational or baseless; many beliefs retain such elements. It's because religious belief has traditionally primarily adopted the role of the basis of an openly hierarchical institution (the Roman Catholic inquisition, excessively theocratic Islamic states today, etc.), or the basis of other negative influences that have the effect of causing intrusions into non-religious elements of life, as noted by the cartoon, that there is opposition.
