My sister is going to be 16 soon, and she has been dating this faggot for 8 months now, i just found out, my mates think i should accept it and let her do what she wants, i disagree - the last thing i want is a slut for a sister, i will disown the bitch, obviously i dont want that to happen but i have the urge to find him and his brother (if its 2 against 1, i can claim self defence) and attempt to beat them into a vegetative state, mates reckon if do that or something similair, there's a good chance that she will rebel and then defintely will turn into a slut - my reasoning is that she might learn her lesson and concentrate on her studies
what do i do, should i confront him
