For the last time…it would be a breakdown in the trust that my wife has with me. The relationship between us would have changed and I would consider it a change for the worse.
What is remarkable here is that you undermine your own position and don’t even seem aware that you are doing so.
Above you seem to be claiming that there would be objective harm to the trust between you and your wife, but below you claim “that no harm comes from it.”
Notice how you went from ‘how gay marriage harms me…’ to 'It changes our understanding…
The first is entirely acceptable and is a good argument why you personally don’t feel it’s acceptable. But you can’t then extrapolate to include everyone else. Your argument only works for you and those who feel the same way as you do.
The same way that my personal views on fidelity have no bearing on how someone else would feel about it in their situation. Just because I can say it’s wrong for me doesn’t give me the right to say it’s wrong for someone else.
And that is obviously on the understanding that no harm comes from it, so no arguments please that suggest that murder or some such evil is wrong for me but could be OK for someone else.
…and thanks for the support.
When you say…
The first is entirely acceptable and is a good argument why you personally don’t feel it’s acceptable. But you can’t then extrapolate to include everyone else. Your argument only works for you and those who feel the same way as you do.
… you actually have things backwards. The reason any such argument works for an individual IS because the individual has abstracted from general experience. It is generally harmful for others to do X, so therefore it will very likely be harmful for me to do X.
Individuals don’t generally treat themselves as special cases. It isn’t true that “Your argument only works for you and those who feel the same way as you do” as if every subjective individual is just daft and necessarily sees reality through skewed lenses. The reality is that most individuals would claim that the argument works for them precisely BECAUSE they have noticed that the argument applies objectively to most or all people and, THEREFORE, it also applies to them.
I would suggest that your response is nonsensical when you say…
…my personal views on fidelity have no bearing on how someone else would feel about it in their situation. Just because I can say it’s wrong for me doesn’t give me the right to say it’s wrong for someone else.
Why would anyone, including you, hold views on fidelity if you honestly didn’t find them to be objectively sound views? If you sincerely thought that you and your wife’s views on fidelity were not objectively sound, but mere idiosyncrasies, wouldn’t you seek to change those slightly odd perspectives to views that were a little more in line with reality?
I would suggest that your guiding principle that “I can say it’s wrong for me doesn’t give me the right to say it’s wrong for someone else” would be more reasonable amended to: “I can say with reasonable certainty that it’s wrong for me if I could make a general statement that it’s wrong for everyone.” Otherwise, why would anyone entertain the thought that something is wrong for them alone, but not for anyone else? Why would they ALONE be obliged by moral rules and others not? Wasn’t Kant quite clear on this?
The problem, it appears to me, stems from a desire to want to be known as “moral” without being obliged by any particular moral injunctions. Leave the back door open just in case you might need to wriggle out of a predicament, which you did by claiming that cheating on your wife would be wrong (for you) because it would be harmful to your relationship, but not really wrong because it would not objectively (only subjectively?) be harmful to your relationship.
If something is morally wrong, by definition, it is morally wrong for all moral agents.
If it is wrong to cheat on your spouse, it is wrong BECAUSE it is wrong for any and every moral agent to do so. That is the meaning of the word “moral.” Otherwise, it is merely an aberration that affects you and no one else, so no moral implications can be drawn.
