Should I "defend " cryptos or just let people believe media and governments?

Reading articles about bitcoin and in general other cryptos, come always across comments of people criticising cryptocurrencies but it seems they are repeating what medias say.

"Cryptocurrencies are use by criminals or money laundering or other criminals activities, they must be banned "

Criminals use ALSO bitcoin but they are using fiat currency for their illicit activities too, "money laundering " is very common in fiat and a very old habit , ban all the cryptos WON'T change anything regarding criminal activities.

"Cryptocurrencies are bad for the environment must be banned "

EVERYTHING is bad for the environment, YOUR internet usage, banking transactions, printing fiat currencies, DIAMONDS, but I don't see you complaining about diamonds...they are used pretty often for illegal transactions such selling illegal weapons and get paid with commodities, but yet , that are okay with you.

" Cryptocurrencies are a clear and present danger to the U.S. dollar. There is a high probability that the U.S. government will outlaw the use of cryptos as currencies. Sounds far-fetched? The U.S. government did it with gold in 1933"

True!! I was about to buy gold in 2021...ops ....I CAN'T ! About 50.000$ kilo.

Should I try to point out these things or just give up and let them believe what cnn has to say?
