Oh no. Not again.
Dont we have enough references of BTC being tied to illegal activities, terrorism, etc. NO! Fuck that.
Fiat money is also used for the same purposes.
Likewise gold, oil and diamonds.
Fiat. gold and diamonds you can trace, at least in theory. BTC provides really anonymity and helps criminals do their stuff. Why the hell would I support it in any way?
Banks help bigger criminals.
The stock market supports all manner of fraud.
Governments too.
Will you also preach against them?
Will you stop using banks?
Do you have a pension? Insurance? If you do you're supporting a very large illicit industry by way of fiat financial services.
