Everyone's opinion is equally valid, but that also needs to be tempered with respect for the fact that theirs isn't the only one, or the only correct one.
Discussion is healthy, but I think sometimes it would be helpful to know when to agree to disagree, rather than wanting the last word and letting things become a dogged battle of wills, each trying to convince the other... because, inevitably, this winds up being a classic case of the irresistable force meeting the immovable object.
Maybe take a few deep breaths and remember that no one here can possibly know you in sufficient detail to tell you who to be and what to think. You don't need to pursuade people of anything. If something doesn't apply to you then it doesn't apply to you. So you say that and that's an end of it. That doesn't mean it has no relevance for anyone, nor does it mean that other people think it does apply to you. I suspect folks have enough to worry about in their own lives and making sense of themselves to presume how someone they don't know, or are ever likely to know, sees themself or lives their life. I think a lot of issues here stem from people taking things far more personally than were ever intended, or thinking things are directed at them specifically, when actually they aren't.
It would be a shame to see anyone leave over something which could easily be resolved with a little tolerance and understanding from all. I hope you reconsider. When all's said and done, regardless of differences, everyone is human and deserves the same courtesies.
