This leads you to believe that every lefty is a communist, rejects 'sound money' and supports a strong centralized government. But that's not the whole picture. I consider myself to be an anarcho syndicalist - which is pretty lefty - and I don't have a problem with Bitcoin. Quite the contrary; I support the replacement of centralized hierarchical structures by distributed democratic structures. Be it financial, political or societal.
'The left' is much more diverse than you might think. Don't let yourself be fooled into thinking that there's only 'left' vs. 'right'.
So, may I suggest that the dislike of decentralized systems correlates more with a preference for authoritarian systems?
Anyway; about the rest of your post:
> [...] like bombing brown people [...]
I think this is uncalled for. It's a strawman deflection and not a very good one at that. Warmongering has been a favorite past time of all sorts of governments, not only leftist ones.
> It's a rejection of science to do so.
How so?
> But this kind of false claim, that is repeated over and over and over again is just not acceptable.
> [...] most bitcoin is mined by renewable excess energy [...]
Do you have any pointers to refute the claim? Can you give me a link to some numbers?
Looking forward to hear from you!
