“if a boy and girl, who never met each other, were “pen pals” and wrote platonic letters to each other every day, would that be okay? can he/she excuse it with the excuse that maybe the pen pal is not being honest about his/her gender?”
No, that would definitely not be a good idea. However, I think that this situation is different because A) it is in a public forum and B) there are moderators here that will remove any inappropriate comments.
