Even if I take religion as hazardous they aren't equal on damage, for this reason I keep a shitlist based on their irrational doctrines:

#1 Islam
-violence
-convert or else
-gender discrimination
-homophobia
-violence towards animals
-slavery support

#2 Hinduism
-gore practices on some sects
-chast system and social inequality

#3 Judaism
-violence
-homophobia

#4 Catholicism
-violence
-convert or else
-gender inequality
-homophobia

#5 Christians (protestant)
Same as #4 but in a bit less extent.

#6 Xintoism
-chast system

Out of shitlist:
Buddhism
Taoism
