Original post by CableI wasn't trying to compare cheating to rape lol. But still, I think it's a good point.
If we are to use your logic, we should respect someone who raped someone just the guy was in a bad mood and wanted to vent it by raping someone. I mean, it was just a "silly mistake", right? Surely, the rapist could have changed after his time in prison and so, everyone should treat him normally? And in fact, if you happen to know the guy, you would let him pick up your daughter (hypothetically) from a nightclub and bring her home?
It doesn't matter what the circumstance. It usually boils down to a problem in the relationship or s/he being attracted to someone else. The person should have the respect to be able to try and work with his/her partner to make the relationship work or at least break up with him/her before getting with someone else rather than doing it behind their back. The fact is that s/he makes a conscious decision to cheat when s/he doesn't have to just like a rapist made a conscious decision to rape someone.
And the fact that s/he has a history of cheating (especially if it's recently) shows that we have to be very careful about getting into a relationship with her. Just like people would be very careful about interacting with a rapist because even though he might have changed after prison, the risk with him is still much greater than someone who hasn't been convicted of rape (yet). That's the point of the rapist analogy.
The job application analogy is also good as well. An employer will employ someone with a better history that shows s/he's perfect for the job over someone with an inferior history. That doesn't mean that the person with the inferior history/experience can't do the job. But the person with the better experience is more trustworthy.
Likewise, I'm not saying "once a cheat, always a cheat". But at the same time, it's a lot riskier to get into a relationship with someone that has a history of cheating compared to someone that hasn't cheated (yet).
