rude comments?? JUST WHY???

I've been part of the glow community for a while, and the last couple of weeks I noticed how a few ladies (1-2 ladies specifically) seem to cannot help themselves to comment rude/obnoxious things on the ppl's post...
I'm sorry but I'm not quite getting the whole idea behind those comments?
We are ALL on here with either the hope of becoming pregnant, or to have others support is along our ttc journeys etc.
No need to break others down or be  rude about their questions, no one is perfect in their journey to becoming a mommy.
The golden rule still stands: if you can't say something nice/supportive, rather keep it to yourself. 
Hugs and blessings to all ttc xx
