I'm not sure what your point is, to be blunt. It seems like you wanted to make some weird argument about the semantics of the word "abuse", and are now implying one of:

1) Beastiality isn't sexual abuse

2) Beastiality laws are pointless because it was already illegal under existing abuse laws (it wasn't, as we've repeatedly discussed)

3) Sexual abuse requires physical harm

all of which are pretty gross (1,3) and/or pointless (2). I don't really feel the need to argue any of this any further, so I'll leave you to it.
