What’s with all the momma drama? Can’t we just all find common ground as mothers and get along?

I see arguments between mothers, day in and day out, all over the internet. The arguments about being a stay at home mom vs. a working mom or using disposable diapers vs. cloth diapers. The arguments even have further subdivision, once you take a closer look on each side. When did modern day motherhood get so confusing and overwhelming? What happened to women coming together and supporting each other? I feel like now that opinions can be quickly typed and shared online, with easy access for the world to see, the judgment and criticism towards each other are just free flowing. I’m obviously all for sharing ideas and opinion, but does it really need to be in rude and hurtful way?
