We can't though, can we? We can only sing "Kum by yah my lord" if we sweep the issue under the carpet.
Of course you don't get deleted, badvoc - that's the art of passive aggression. There's nothing 'active' to delete, it's more the tone and often what is not said, than what is.
In all honesty, I think it's the carriage returns that make you sound more aggressive than perhaps you intend? Take this for example:
"Sigh.
No.
I dont think I know everything.
You said yourself your post was ill advised. I agree."
It sounds snippy and narked. However, if it said:
"Sigh. No, I dont think I know everything. You said yourself your post was ill advised. I agree."
It still conveys frustration but not so much 'bulldog chewing a wasp'.
I'm not picking, btw, I just spent a bit of time wondering why I (and others, it seems) perceive you to be aggressive in your tone, yet you don't. I think it's the carriage returns...they make your words seem much more dogmatic than (perhaps) you intended.
Sticking to the TH thread won't change the fact that the TH thread has become a no-go zone for posters who aren't in full agreement. It won't help the fact that indigo thinks it's perfectly acceptable to tell parents that there is a cure for dyslexia, if only they'll spend money (not only the fee, but the cost of travel) with Robin.
It won't change the fact that schools are trialling therapies without the knowledge and permission of parents, which Indigo has encouraged and promoted, despite this board being 50% about parents who can't get team working with their schools. Of course, because Indigo agrees with it, it's fine in this instance 
Just because Indigo is nice, that doesn't mean that she is infallible. It doesn't mean that she is above the rules MNHQ set.
