Ok so lets get your returned bullet comments out the way.
Yes we did have similar thoughts about a thread in AIBU regarding a step-mum who had issues with her teen SS spending time with his dad (her hubby).
You got in a ruck with some one , cant remember who and said you was gonna leave.
YES I did pm you to say dont leave
you then accused me of being a hypocrite , slated me and wrongly accused me of being the author of a post which accused you of being a stalker.
I was a bit
but posted to correct your mistake.
YES you did apologise when you realised your mistake.
But the last post of yours on that thread was also pretty much a generalisation that everyone in MN were bitches with no lives.
Again a
from me .
Because I was /am newish I was unsure as to why people seemed to be a bit miffed with you and naively thought it was a bit OTT.
However after reading this OP I am at a loss to understand why you would bring up the subject again.
YOU REALLY DO LIKE A RUCK DONT YOU.
As you know I am a step mum, I also know that just because someone IS a step parent does not automatically make them bad.I would no more judge every step mum in the same way as the one who had probs with the teen than I would judge every teenager alongside a teen with an ASBO.
The problem is not with the label its with the person.
So before you say I was nice to you before and now I'm being mean, lets make it clear that is not my intention, I will call it as I see it no matter who the poster is , friend or not...If its in AIBU then its open for discussion , debate, applause or vilification. Makes no never mind to me.
You said:
that you know your child's SM is mean because you are still friends with your ex's family and they tell you.
WTF!!! Why why why would they tell YOU such things if not to cause trouble, If there were genuine concerns SURELY they would tell your ex.
You have no more right discussing the SM with your ex's family than they have with you.
Its unfair on the kids. They will pick up on the obvious tension and their loyalties will be so torn , That is unfair and cruel.
Suck it up and behave in a way thats better for your child even if it means being gracious about their fathers partner .
you say in your 19:21 post
I don't know how you can judge me, both of you, you don't even know me!
Ok fair comment except you are quite happy for people to judge the step mum whom
they dont know either 
see now THATS hypocritical.
Some one said "You've asked for people to reinforce your opinion of stepmothers."
Aint happening chick, YOU cannot possibly ask anyone to generalise about all stepmothers like that.
Each are individuals, good bad and indifferent....OMG!! look at that, just like real mummies.
P.E.O.P.L.E. everyone an individual.
Someone else said :
Though it's not entirely clear what you are asking.
Well after the way you rehash the same old gripe, the same anger and the same old response( yep I thoroughly expect a vicious retort to my comments)
I can only assume that you want attention and rather like a naughty child you will do anything , including irking people just for the hell of it because any attention , even negative is better than NO attention.
I find this incredibly sad, surely there are enough topics or places to go where you can discuss your issues without pursuing a ruck, Maybe then you will get the response you need rather than the responses you want.
I have not "fallen out" with you SPM, but how you take this post is entirely up to you, somehow I sense you will not take it in the way it is meant, because there would be no ruck in that, would there?
