Excellent post Jupiter
I see that Teacher has followed Felicity to her other thread and been similarly nasty over there too.
Felicity some tips for the Newbie:
There is an interesting function called Advanced Search (often referred to as AS) . You can look for specific topics e.g. Breast feeding or for specific posters such as for example "TeacherandFeminist" It can be quite revealing. Teacher herself has only been posting (under this name at least) for the last day or two.
Name changing is a particularly interesting feature of MN. It's useful as it allows you to namechange regularly to prevent anyone having too much history about you or to separate your interests between posting names e.g. You might prefer to post about your experiences as a University lecturer under one name and your experiences as a parent under another.
However some posters do use it to be horrible and start fights (we call them Goady Fuckers) It's OK these are not generally well lived or respected posters.
On that note may also find the report function quite useful.
Have a look at the MN abbreviations list:

The accepted term for husband is DH (dear husband). Your baby will be either DS or DD (dear son or daughter).
DFOD (do fuck off dear) can be useful, as you may have found from this thread. BTW Swearing is allowed on MN. Blanking out swearing (e.g. F*ck) tends to be poorly received.
AIBU is one of the most read boards but it is also known for being fairly blunt and plain speaking. Not a place to post if you are feeling delicate.
There are lots of other boards across MN with all sorts of posters and little communities. Lots of them completely unrelated to parenting.
Not everyone here is a parent. Not everyone here is a woman. Non parents and men are perfectly welcome on MN and provide interesting and thought provoking contributions to the site.
There are MNers all around the world so no matter what time of night you post there is usually someone awake somewhere to provide advice or hold your hand.
