Your poll can not be answered because it is missing the important part about "time". In other words it is unclear when you ask "What are your thoughts on increasing bitcoin's block capacity?" when do you mean?
For example if it is a hard fork to increase block size in the future when the need arises, then my answer is a big fat YES. We definitely need to increase the on-chain capacity at some point but the important part is the "at some point" part.

Right now we do not need a block capacity increase. The reason is pretty simple: the adoption hasn't grown enough for the current block capacity to not-be enough for the legitimate usage. Since I have to dot all the eyes and cross all the tees: Legitimate use is anything that is not a spam attack, meaning where people use bitcoin to transfer money or in other words when Bitcoin is the "peer to peer digital cash system" that it was intended to.
When it is used as "cloud storage" it is considered abuse and the transactions are spam. Meaning right now that the congestion is caused by abusing the protocol to perform an attack on bitcoin, this is not natural and the exploit should be fixed instead of increasing the capacity to let bigger spam in.

P.S. I don't think increasing block capacity has ever been a "taboo" as some like to exaggerate it. HOW it is increased has been the source of a lot of disagreement.
