@Arella Mae,
...because
Irrespective of interminable "religious wars",
when I'm inconvenienced by security queues at airports,
or
when I watch army chaplains blessing the troops,
or
when I think of forced child circumcision,
or
when I realize that people are dying of aids because the church banned condoms
....etc,etc....
.the word "believers" seems to spring to mind !
And BTW "believers" can be equally applied to demi-gods such as atheistic dictators as well as mythical celestial constructions.
In short, "atheists" are inconvenienced, worried , and upset by "believers",
hence their vocal participation.
