I'd say one could have their cake and eat it too, that is, avoid having to avoid horrible vile RP and also not have to break character is to have your character reasonably be able to is to have them object to the same things you find it unacceptable to RP. Now, this isn't to say you should project all your OOC beliefs on to your character as this bad RP, but I don't think you're sacrificing any creative integrity by saying "Y'know, I'm not a horrible creep that wants to RP my character raping somebody, so I'll have them think rape is bad." Or something along those lines.
roleplay?
