I hope you don't mind me harping in on this post and making this comment. I think your right that some people take your aggressiveness towards certain subjects resulting from frustration as soap boxing. (Now I will say I'm still confused over what definition is being used with this term. I've asked a couple of people to provide a definition of the term and have not received a reply.) So I'm assuming this is part of the definition they are using with this term? I don't think its the right usage of the term? But I don't know since no one provides a definition of the term as far as their usage.
My opinion is your on the right track with your changes. Personally, I see many of your postings exactly as what you describe. A want and desire to discuss these events objectively and critically. This may have been possible years ago. But the forum community has changed. A adage I think is fitting with this situation is 'you can lead a horse to water but you can't make them drink.'
It doesn't do any good trying to wrestle with a horse. I've tried it and you lose every friggin time. Ha Ha So all that can be done is try to lead people to the water. Then its their choice if they drink.
The problem with frustration is it puts the onus of the frustration on oneself. When other people are involved in making choices frustration isn't constructive since they are the ones making the choices not you. It makes us feel as if we do more or present it better then they will understand and choose differently. I don't know about you but that isn't my experience. Ha Ha
Again I hope you don't mind me adding my 2 cents on this subject.
