I was a Jack/Daniel shipper but not a Jack/Sam basher (I've never been a basher of any kind, actually. Critical, like I am with Mulder, but not a basher. *g*) But I did see, as a slasher, the depth of hatred spewed by some J/S shippers toward the slasher, and some of that involved Daniel. I never engaged or had a relationship with anyone who did this, but there were certain places I did. Not. Go. It was scary.
