Atheism and agnosticism aren't mutually exclusive.

Your use of "free will" is ill-defined. There are two completely different ways in which people use that term. I suspect that you haven't thought it through very well - the fact that many intelligent people believe there is no free will should be a clue that you've missed something.

I've done vegan/meditation/ayahuasca/weed. I doubt yoga would be enough to change my mind.

Your description of matter as being "cold" is just an appeal to emotion and to accepted norms in Western society. Material isn't "cold," nor is the existence accepted by most atheists.
