Thanks, always have time for well organized pedantry. So 'weak' atheism is basically agnosticism with Occam's razor.
'Agnosticism is lack of knowing on the matter.' is a nice point, it's right there in the word. I'm not sold on '“Lack of belief” is specifically an atheist trait.' though, can easily apply to agnosticism as well (or not for those that do believe).
Personally, I'm happy to eclectically pick and choose wisdom from many religions (shame they so often ignore the source material in practice), but that doesn't make me believe in god/s, merely the psychological usefulness of some ideas. I'm happy to believe in said usefulness even without evidence beyond anecdotal, people are such a mess of contradiction.
