*Aren't some of you sweet! Hating on cultures that have their children's ears.
If you hate something doesn't mean you can undermine someone else's culture and parenting, it's not CHILD ABUSE!
Having you're baby's ear pierced does not = horrible parent.
And yes some of you do need to get over yourselves, acting all high and mighty because you didn't have it done for your child, while your all it...
How about feeding children a snacks that contain harmful chemicals,food dyes and pesticides one could say that child abuse!
Giving you're child take away, letting them drink coke that's harmful to their insides.
Isn't that child abuse? The child has no choice what it eats??*
Nobody said anybody's actual culture was terrible or that they're 'horrible parents'.
We're saying ear piercing is totally unnecessary, and I believe in challenging cultural norms when they don't serve us - especially women - well. As someone said, why take a risk just so people know your baby is a girl? Why is that important?
And as nobody's yet brought up feminism, I'll say that it smacks of pushing societal/cultural expectations for what it is to be a 'pretty girl' on babies. We look 'pretty' without bits of metal stuck in us. This is my biggest issue with it really.
And I do think people should be conscious of what they feed their children and not knowingly feed them anything that might harm them but we can't actually survive without food. It's more trappings of patriarchy. We punch tags into the ears of dairy cows and we do the same to our women 
. At least the tag in a cow's ear has a function.
It is possible (and desirable IMO) that the bad bits of cultures can be got rid of as we grow and learn, because culture isn't just about external appearances, it's much deeper than that. Religions do away with certain traditions over time. People often use external symbols to feel like they belong, but isn't it better for your sense of belonging to come from a deeper connection of shared wisdom and experience?
Also all these anecdotes of 'I had mine done and I didn't die' - Surely people know you can't really take that as evidence of it being harmless (especially since a PP nearly died from hers). 35% of piercings get infected, you can also be allergic to the metal, and technically it's a trauma, a wound that the body has to heal. So it never fully 'heals', and the cheesy stuff that accumulates is your body trying to push out the foreign object. If you want to change your hair colour you do a patch test and the risk is printed all over the box, yet you can walk into Claire's Accessories and have someone with the most basic of training do something that is more painful than minor surgery your fully-qualified doctor might perform, and for no reason other than wanting to fit in.
