Totally agree OP. It's awful showing off and I feel a bit sorry for those who haven't managed to create the perfect family set up and feel bad looking at these curated images. Those who haven't managed to have children, or find the perfect man to have babies with. Those whose husbands have died leaving their children without a father.
I must admit I am one of the lucky ones in this area of life but no way would I gush about it online with boastful posts and ohotos. Just keep your feeling of luck to yourself I reckon.
What a load of absolute nonsense.
So should anyone who has children and who is happily married never EVER speak of their husband and children to single childfree people then? And never ever post pics of them on social media, lest they offend the eyes of the permanently single?!
And should people never wish their dad happy fathers day, or their mother happy mothers day, in case someone on their friends list has lost one of their parents? 
FFS, if it offends you and upset you THAT much, and you are so fragile, then unfriend or unfollow them!
I agree with a few previous posters, that this is a nasty, mean spirited thread full of bitter, mean-spirited little individuals who HATE to see anyone happy.
The jealousy is strong on this thread. Maybe you should all deactivate your facebook accounts, because God FORBID you see anyone posting pics of any happy times they are having with their family and friends.
And as for the poster who ranted about people having the AUDACITY to post a collage/some pics of their deceased relative, and put a message of love to them, mocking them and calling them attention-seeking. WTAF is wrong with you? 
So, some people don't put anything on social media when a loved one dies, and some people do. People are different. Deal with it. As I say, if you don't want to see it, deactivate your bloody account!
There are some really unpleasant, bitter, vitriolic posters on here.
Have a word with yourselves FFS!
