It's strange to me that some Bitcoiners are fiercely anti-Monero, and that some Monero bros are anti-Zcash etc.

Also, smart contract chains enable powerful decentralized applications (particularly the privacy projects).

Sure, >99.9% of coins are money grab ponzi scams, and deserve to be condemned as "shit coins", but the remaining <0.1% are worthy of appreciation.

Public ledgers like Bitcoin have some advantages and private ledgers like Monero have others. A good carpenter needs more than just a hammer.

Satoshi, Finney, and many other legendary cypherpunks supported privacy coins.

My assumption is that this is due to BTC "number go up" primacy and tribal/religious demonization of outgroups.

Protecting the naive from scams and rugpulls is the strongest BTC Maxi argument I've heard so far, but it doesn't apply to alternatives like Monero.

Can anyone argue that an alternate timeline where Monero had the dominance that BTC currently enjoys wouldn't be better for the future of freedom?

The main reason Bitcoin is #1 is because it was the "first". The secondary reason is the religious tenacity of the Bitcoin community.

Not hating on BTC maxis, just sharing my perspective. I doubt Bitcoin would have gotten this far without the Maxis.
