It's just weird for me, because I mostly like het fic and het rp in the days when I did rp. (Mostly, but I do write some m/m and more f/f, and I did have one beloved slash rp pairing that I still miss.)

But anyway, there really aren't characters where I say "No way could that person ever go with someone of the same gender." Sometimes I don't particularly ship them with anyone of the same gender, but it's not because I can't see it happening.

tl;dr I just really don't get that argument even though I'm not much of a "slasher" per se.
