yes, beliefs are our perceptions of reality/philosophy that we think are true. belief =/= religious faith. believing the earth is round or flat are beliefs too. believing that 1+1 is indeed 2 is also a belief. saying "it's a lack of belief" is dumb. though it is not a belief system, it has no teachings or dogma, it simply means believing that there are no gods. in the west we have a skewed view of atheism that it must default to materialism or rationalism, no you can be an atheist and not hold either of those two positions.   atheism itself has no claims on homosexuality, you can have atheist nations such as sea nations or belarus goverment that are anti-lgbt, most atheists in the left are progressives sadly, but that isn't always the case.   bad counterargument, that is an american progressive larp priest who are a minority in the general christian population, on average christians oppose lgbt, their bible condems it.
