It's a religion (for most Buddhists).

Everyone here seems to equate Buddhism with the western humanist view of it which is a little limited. You could possibly say that Zen is more of a way of life.
There is a huge faith aspect to Buddhism, it's not all blind faith, a lot of it is developing faith empirically by trying Buddha's teachings out and deciding if they work or not. But the Buddha never rejected blind faith either. If it works for you and makes you happier then it's OK.

A lot of Mahayana Buddhists work on receiving blessings from Buddhas (Mahayanists believe anyone can become a Buddha therefore there are lots of Buddhas). The only thing Buddhism as a whole lacks is a creator other than that it ticks all the religious boxes.
Of course their are Buddhists and Buddhists and for some it is more akin to a way of life but these are the cherry pickers rather than the followers of what the Buddha taught.
