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.

Do you have any pointers to refute the claim? Can you give me a link to some numbers?
Looking forward to hear from you!

The largest cost of cryptocurrency mining is electricity. Electricity energy is the cheapest so naturally many Bitcoin mining operations are built in places that are over producing energy. The cheapest excess power tends to be hydro power, Bitcoin can be viewed as a small subsidy for new hydro electric projects when demand has not caught up to supply.
>Bitcoin mining operations – essentially massive and powerful datacenters - are located internationally, and usually concentrated where the cost of electricity is cheapest. That’s because the cost of electricity can make up 90-95% of total ongoing mining costs. These datacenter mines can be found in numerous countries, from the Republic of Georgia to Iceland, to Malaysia and Venezuela. The largest share of the miners are located in China, close to the border with Tibet where cheap hydropower is relatively abundant. - https://www.forbes.com/sites/peterdetwiler/2016/07/21/mining...
>Haobtc is also operating hydropower mining facilities in Kangding. Eric Mu, Chief Marketing Officer at Haibtc, said it cost a lot to build a hydroelectric plant, but later on it does not have a lot of maintenance costs and can use electricity cheaply. -https://steemit.com/bitcoin/@jycloud9/china-builds-a-hydropo...
Bitcoin miners move to places with very cheap/near free power. They can park the datacenter right next to the power plant so very little is lost in transmission.
is bitcoin democratic? Isn't a "might makes right" system?
To perform this amount of hashing with this example it would take 3TJ. Or for comparison, the energy in about 170 barrels of oil, for one Bitcoin transaction.
The numbers may be a bit off, but they're not off by a factor 100, and my house for sure doesn't even need 1/100th of this to run a day.
This is not how to defend bitcoin.
