I'm against forcing unnecessary medical procedures whose effects can't be reversed on infants that can't consent.
People can stop eating meat, but they can't stop being circumcised.
That doesn't excuse being force fed meat. We have to accept that parents need to make certain decisions for their children at young ages, particularly decisions that don't have significant negative consequences.Most of those decisions are not irreversible. Also, unless you're literally shoving the food down the child's throat I don't know if it can be considered force feeding. (not to mention that it's highly unlikely a very young child would be a vegetarian unless their parents are also vegetarians)
