this is a discussion of differing ideologies: should rules be absolutes that must be universally obeyed or should we use rules as guidelines (which gives them some flexibility) to maintain a particular system or ideology?
allowing sexual discussion, even under these circumstances (rape) would be subversive to maintaining the ideology and spirit of the site. in this realm, all sexual discussion (regarding real world encounters) is off the table. wizchan defines itself by its separation from real world sexuality so discussing it in any context would go against the ethos of the site. you shouldn't talk about politics in a golf forum. you shouldn't talk about south park in an anime forum. you shouldn't talk about real world sex in wizchan.
however if (like me) you view rules as guidelines rather than absolutes, then victims (of rape) may be eligible to post and participate in the community. if their beliefs and principles are in line with those of the site, then I would argue the violence done against them should not preclude them from joining the community and participating in discussion. i don't believe we should penalize people for factors outside of their control. if you post within the guidelines of the site then you are neither a disruptive or destructive influence on the culture of the board. but like i said before, this board is dedicated to a very particular human niche, so even though i believe rape victims are eligible to post here, they should still not discuss their real world sexual encounters here. this just isnt the place for that.
in the end, its a personal choice whether you post here in spite of the fact you have sexual experience. some users don't believe you have the right to be here, some do. either way, i don't think you should expect the site owner to change the rules or definitions contained therein. the site rules are intentionally strict to maintain the niche nature of the board. wizchan is a very particular facet of humanity that requires a higher level of gatekeeping that other communities.
