You're taking one line I wrote and applying it to everything. I've made a bunch of other statements in this conversation about how I prefer mixed groups, not only of sex but of ethnicity too. One nice side-effect of a mixed group is there might be some dateable people in there, but it's not a given, and it's nice to have a mixed group (IMO) for many other reasons than just sex or seeing pretty faces, but I don't see how it's wrong to want to work in a mixed environment and have that possibility if you're single.
