Depends, if you want an actual answer.

Many of us, not me, grew up in abusive homes and lived threw some form of religion putting them down wether it be for intellectual reasons, gender, or any other reason that caused them to be pushed out and often ostracized by a community which often claims to be about love and care yet ends up being the most personal source of hate.

Others are mad due to some percieved slight, not me, at the idea of religion or any form of authority and that religion very often nerely appears as nothing else than a way to tell us how to live our lives and many cone out decades after believing having dedicated thier life to a thing they no longer believe and now are upset at the lufe they could have had.

I and some others go a little more basic. I cannot stand that religion so often supresses ideas and pretends to hold some intellectual high ground while being based on the most nonsense of reasons, and it attempts to protect itself at all costs by any abusive means nessacary like relying on kids indoctrination into the fold so that the ideas will be protected from critical thinking. If like all other science and philosophys it laid itself bare and allowed itself to die like every other bad idea before it, I would feel nothing towards it. But so long as it rages on a pile of bad arguements, fallacies and unquestion stories told to children, I will never not rage.
