Sin

I rode passed a young woman wearing a t-shirt that said 'I love sin.' Presumably the sin is something she delights in which runs contrary to the moral norm. It's likely to be sexual but it could be stealing from her boss.
It's when it turns against her that her love for sin goes south. She's left for someone else or she's caught with her hand in the till. She loves sin until it hurts and then she hates it as she should.
But there are sins she could never love. Being fired from a job she desperately needs just so her boss could pay himself more, or being falsely accused, or having a family member violently assaulted.
On those occasions, she could rightly expect the moral norm to speak out in her defense, whether from a church pulpit or in a court of law. On such occasions her t-shirt might read 'I hate sin' and others not knowing, might think her a religious prude.
It can be rightly said of most of us that we love sin until it turns on us and when it does we hate it. We expect it to be decried in our churches and in our courts of law. We are angry when neither speak up, we are betrayed when both are silent.
