I think it's reasonable to give your own opinion and respond to the opinions of others -- much as you just did. It seems somewhat disingenuous to question whether responding to someone other than the original poster, who you happen to disagree with, is reasonable at the same time you're doing it.
For someone asking a question like rope monkey's, disagreement, even heated disagreement, is valuable to see, because it gives one the real sense of how people, including rope monkey's partner, may feel and react to a topic. Denying the questioner that is a disservice.
We should all be sweetness and light and say "oh, honey, just do what makes you happy and what you think is right" -- then when the partner finds out and explodes the poor questioner is left thinking "but so many people told me it was okay"?
Do that and they might as well close up shop for everything but the Fun & Games posts, because the site'll be useless to anyone who actually wants the whole spectrum of opinion.
I think the essence of so many posts on this topic has been simply that while you may consider it a "slightest hurt", the person's partner may consider it a major betrayal -- and their feelings and response should be considered.
There are two people involved in any relationship and that means making accommodations for how the other sees things as well. If the two views are incompatible, then the two people probably shouldn't be together -- but to simply ignore the other person's views as unworthy of consideration shows a singular lack of respect.
How would you view a dominant who told his partner "I know you have a hard-limit against piss-play, but I like it and I think it's 'slight' so I'm going to do it anyway"? This community would "tear into" such a person and "crucify" him -- one only needs to look around the forums to see such.
Why should the non-BDSM partner's limits be any less respected?
Because the limit is unvoiced? Nonsense -- some limits are implied, even in BDSM and traditional relationships don't explicitly state their limits ... should they be ignored simply because it isn't the common convention to state them?
Because it isn't physical harm? Again, nonsense -- because a BDSM limit on verbal humiliation causes no physical harm, but would still be considered wrong by the BDSM community.
Trust, consent and respect of a person's limits -- so important in the BDSM realm, but okay to ignore if the person being harmed is not a member of our community?
I count five questions posed in this thread toward that post, two personal opinions in opposition and one partial agreement. The closest I see to "condemnation" is a comment that something is "a little counterproductive". One would have to be pretty touchy, I think, consider that condemnation.
Regardless, the post in question said nothing about the partner's knowledge or agreement, only statements that "I decided", "I wrestled with", etc. Nothing like "we talked", "we decided", "he agreed" -- I stand by my statement that the conclusion was reasonable, especially in the context of a discussion like this.
If your partner feels that ogling barmaids is a violation of some term of your relationship and you then do it anyway without her knowledge or consent, then you've violated her trust and have not respected her limits. If she doesn't like it, but you've made it clear you're going to do it anyway and she's accepted that, then ogle away.
If she decides it's okay to suck some other guy's dick (or something you'd object to if you're okay with that), then it's okay for her to do it and keep it from you because you "don't need to know"? There's a formula for a relationship based on mutual respect. Now, maybe you don't want a relationship based on mutual respect -- and there's nothing wrong with that if that's actually what you want -- but the original post concerned traditional relationships and this is part of those.
My partner trusts me not to give them an STD because she thinks we're monogamous, so I always use a condom when I have casual sex with strangers in bars. In my view, my actions don't detract from her safety, so it's all good. Right?
The private bank account's fine if they've agreed to have private bank accounts. Why the hell is it so hard for people in a community that talks so damn much about trust, consent and limits to accept that trust, consent and limits are important?
Are you actually expecting legal definitions to apply to interpersonal relationships? That's sadly absurd.
And your parental analogy is specious. Not all relationships are the same.
Want to use a parental analogy, fine: Your parents get old and give you power of attorney, they trust you to be a good financial steward of their retirement money because they've gone a bit 'round the bend. You start betting the horses with the money and don't tell them about it. Even if you win, you've violated their consent, betrayed their trust and broken their limits. Deciding "they don't need to know" is okay?
The answer to that question that everyone here has given is: Yes, if your partner is aware of and consents.
What's been criticized is violating trust and not respecting limits.
And, frankly, asking questions, which is what most of the responses to Mandy's post were doing, is not lynching or crucifying.
As for broad opinions, some opinions are morally wrong.
If you can offer a different position and defend it, that would be valuable to the discussion and the original poster.
