Ive found that some people are politically against Bitcoin and therefore think its ok to say whatever they can to stop it.
The real mystery to me is why someone would be politically against Bitcoin if they aren't rich. Are fiat currencies so good for you that you should seek to fight all alternatives?
You're scratching the tip of the (rapidly melting) iceberg with that.
Why do people in the poorest states of the US - those states one can affectionately refer to as "The Arc of Republican Poverty" - consistently vote against decent public health care?
Why do people who will never have two nickels to rub together consistently elect politicians who give away the public coffers to the wealthy while at the same time raising taxes on the middle class and even the poor?
Why do politicians all over the world get elected by promising to hold the banks faultless?
Let me refine your question a little bit:
How is it that people are consistently convinced to vote against their own self-interest?
