To be honest its something I see often on MN and never have anywhere else (and I have been on multiple international pregnancy/parenting forum for the last 17 years).
Its like some people here are militant on telling everyone woman to have a termination, its some weird MN 'pro choice' virtue signalling (all though the opposite of choice if you are TELLING others what to do) but comes off far more offensive when theres not one ounce of suggestion from the OP that shes unhappy with being pregnant.
It can literally be like
'OMG I so happy, I have always dreamed of being a mum but we tried for years and never got pregnant even had 2 failed rounds of IVF. Now I'm 40 and me and DH have just downsized from a 3 bed family home to a little cottage because we thought it would never happen for us but just now found out I'm finally pregnant. I know its early and things can go wrong but its such a shock surprise, any cute ideas on how to tell DH when he gets in from work?'
and within 1 page of responses you'll have some twat say something like
'You should terminate, your poor DH didn't consent to this 'accident' baby (was it really an accident, babies don't just happen) and you clearly can't support a child in a small rural house plus you'll be nearly 60 by the time they go to Uni and what if they're disabled because your older, its just not feasible'
Its quite an amazing and uniquely MN phenomenon. Luckily I think most people who aren't first time posters know these are just random outliers that pop up to rock the boat and most responders are actually sane.
