All belief systems bring judgement.
IMHO all belief systems bring about the desire to judge others, whether these belief systems are political, religious, cultural etc.
For example, "I don't believe in smoking, so therefore people who smoke are bad".
"I don't believe in god, therefore all who do are unenlightened and less than me".
"I believe in conservatism and capitalism, therefore all that don't follow this belief are stupid, wrong and less than me".
"I don't believe in eating meat, therefore all that do are unenlightened, wrong and less than me".
These are not necessarily my beliefs, but merely examples of how being attached to certain beliefs create judgement of others. This is also not an attack on anyone who does hold these beliefs, just an observation.
