This feels like the die-hard old Christians trying to make a law against nipples, because of the children that'd probably see one or say the word 'nipple.'
Either way, removing ERP would be silly, solely because it's also role-play. You may not like it, but real life lingers on sex a lot too, especially in low class neighbors. Now, the situation in LSRP was unique, and I'd even say that I grew annoyed by ERP because prostitutes would drive Bullets, etc. but then again, that's the incompetence of the previous server.
Let's not forget that street gangsters, or just rap music in general glorifies sex, talking about eating and tonguing pussy, moaning during the beat or how much she gives head. Do you find them just as weird?
Don't pull the "people that do this shit are weirdos" because you're just as weird for both giving a fuck about it, and for role-playing murders and doing drugs. It may not be the same thing, but anyone would be having a chuckle at you for doing these things— especially role-playing the street gangster. People'd just look at you funny for being a wannabe gangster, just like you'd see people doing ERP, as weirdos.
