Everyone has religious convictions...only about what is the question. No one finds his own religious convictions unreasonable. People who claim to be non-religious are usually engaged in a personal struggle with certain specific historically known forms of organized religion that they have encountered or heard about, and they tend to be rather religious in their anti-religious zeal, I find. ;-) Their clear desire is to convert the unbelievers (or just ridicule them, which is always fun if you can't convert them), and it is founded upon their certainty that theirs is the "better way"...or perhaps, the only way.

Anyone who thinks his way is the universally "best" way for people to be...or the only way...is wrong, in my opinion. There is no best way. There is no only way. There are numerous ways, and all of them suit certain people to a "T".
