Actually people are always afraid of weird novel things, btc is not an exception. I'd rather not consider haters as a threat to btc, since any project needs to be continuously criticized in order to become better... So, in general, telling bad things about btc won't lead to banning bitcoins, and vice versa: if any hate speech against btc will be banned, it doesn't mean that btc itself won't be banned at some point. Cryptoprojects are not the thing to adore or to hate, they are just financial tool...
I do not even see how the OP linked those two subjects together as they have nothing to do with each other, if people out there want to criticize bitcoin and its users then let them, if they do not think bitcoin serves any function they can actually use for their benefit then most likely they are right, as someone that does not care for their privacy and that is fine with the possibility of the banks stealing their money one day out of nowhere and that likes for their transactions to be monitored to the smallest detail has no use for bitcoin.
