There is no we in atheism. Stop doing that!!! There are atheists, who believe in a world view, that makes atheism a positive part of a systematic world view, but that is not required if you are an atheist. That is there inter-subjective belief system.
So here is your problem and how your argument is wrong:
We have better things to do than meet up.
- We is not a positive qualifier, because atheists are only a category in a negative sense. We don't believe in gods and deities.
- Better can't be done for a we, because there is no objective morality and thus no better in universal sense for a we.
So stop claiming your own subjective opinions as universal for a we.
