Actually, I'd prefer it if Bitcoin and pornography remained separate for now. Bitcoin still has a reputation for being associated with shady and often illegal activities such as drugs, gambling, hackers, assassinations, money laundering, ISIS, etc. Do we really need to add pornography to the list?
Of course fiat can be used to purchase porn and drugs too but fiat can also be used to pay your electricity bills or groceries at the supermarket - i.e. legitimate stuff. BTC doesn't quite have the same level of support yet. Businesses that accept BTC are still quite rare and having pornography become such a large part of the fledgling Bitcoin industry at this stage is probably going to hurt society's perception of the currency and possibly negate whatever economic benefits it may provide.
Anyway, that's just my opinion.
Actually, I'd prefer it if bitcoin was adopted by the porn industry, because it shouldn't be shameful to use it with anything. You can also pay your bills with bitcoin and if you can buy porn and drugs with fiat cash then why not bitcoin? If we want bitcoin to succeed as a currency then people should be able to buy absolutely anything they want with it... even illegal stuff and that's just up to the authorities to police.
Oh, and fuck the ignorant perception of society. They'll change their mind over time, but then it'll be too late for them anyway.
