Those who support (pro) bitcoin and those who are against bitcoin always have a clash in speech. Those who hate bitcoin see bitcoin as a scam and other crime scheme. So with their view on it they see bitcoin users as scapegoat, criminals and money laundering and some special advisers in the government see bitcoin from this perspective so they advised the government to ban bitcoin in their country. And this cause a social trauma between these two groups.
Upon all these bitcoin is still gaining ground in the ecosystem. Therefore, hate speech cannot do anything to bitcoin again.
Those who hate Bitcoin are people without mind in their heads because someone who has a little knowledge about finance and freedom would accept Bitcoin without any obligation. I would consider them arrogant because they really missed a great invention due to their own stupidity. Those days are long gone when people considered Bitcoin as a scam or something that can go zero in value anytime. Now most of the people accept the fact that Bitcoin is the future and many skeptical people have invested in Bitcoin.
Those people who promote lies about Bitcoin are mostly part of the corrupt system and they just hate the idea of decentralization. Bitcoin is their biggest enemy because it has allowed everyone to be free from the bondage of that centralized system. Most of the governments are against the concept of Bitcoin and decentralization because they want to control others and move them as puppets, but Bitcoin can free them from such bondage and that's why they hate Bitcoin and promote fake news about it.
Bitcoin has nothing to do with criminals because they have been there before Bitcoin and they will remain there forever. Most of the money launderers aren't laundering money via Bitcoin and if you view the statistics of money laundering and other crimes then you'll know that money launderers and other criminals mostly rely on fiat based system. Even if most of countries ban Bitcoin they still won't be able to suppress it because Bitcoin isn't against any country, it's a form of payment that allows everyone to trade goods without any interference from centralized authorities.
Not everyone who doesn't believe in Bitcoin is stupid. For the same reason, we all can't like the same things. Even well-known economists have expressed a negative opinion about Bitcoin, and the opposite too, of course. It's not about stupidity, but its concept and idea don't apply to everyone, and everyone is subject to their own opinion, which they can voice. Thus, claiming that someone is ignorant or stupid for not supporting Bitcoin is a little bold statement to make.
However, it's true that the majority of governments aren't too fond of cryptocurrencies in general due to their decentralized nature; it's way easier to hide money and conduct transactions undercover. This enables freedoms that aren't available with the banking system. Cryptocurrencies have been notorious for the darknet markets, which certainly hasn't helped their reputation, but in reality, these transactions are only a minor portion of the true corruption out there, and cryptocurrencies aren't liable for it.
