It's a well known fact that smokers lead shorter lives than non smokers. Are you advocating the icriminalization of smoking. Hell it is well known that fat people have shorter lives than thin. Do we make fried chicken and pie illegal?....
No a better analogy would be that heterosexual couples that engage in S&M and BDSM behavior are "not normal" Hell they are down right out of the mainstream. I am not talking about the occasional tying up the old lady with a tie. I am talking St Andrews Cross in the extra room, ball gags, leather cuffs, paddles, whips, floggers canes. That is WAY outta the norm. So should breeders who tie eachother up and hurt one another be kept from marriage?
