Yes, the classical definition simply means that you don't believe in a god.
Here's what I would like to see for the future, though:
-activism. A striving for equality and understanding.
I grew up surrounded by racism, class-ism, ableism, sexism, sizism, homophobia and a whole lot of other -ism's that are negative, and detrimental to society, by splitting it up into "us" and "them", and a lot of these are in religion, some are outside of it, but much of it, is passed down alongside religious teachings.
Church and many religions are just rife with these shortcomings, religion obviously has been used to justify violence and prejudice against almost any minority group, from women to homosexuals, to people with different melanin content in their skin, to people who are poor or of another religion.
However, what if Atheism stands for a shedding of these ideas, a discard or all that prejudice that's been handed down through the generations alongside the family Bible, or Koran or Torah. What if we stand up, among the minority groups and say "this is a choice, a choice that represents human equality, a choice that doesn't objectify women or use them as second-class citizens, a choice that won't exclude you because you look different, a choice that won't put you down because you're not rich and white and cisgendered and heterosexual and male and thin and attractive and healthy."
What if Atheism stood for this?
Do you think it would be good thing?
Do you think it would help push the fact that Atheism doesn't have a backlog of tenets, many of which outright disdain so much of humanity?
Do you think, perhaps, that it would help people who are oppressed and discriminated against, see why religion isn't a good choice?
What do you think?
Do you agree?
