Did she stamp on the baby?
No. The daily mail bought the (faked) pictures because it's readers like feeling anti-foreigner sentiment amongst other emotions (anti-gay, anti immigrant, medical fears etc etc) - it's one of the main reasons they buy the paper and they expect anti-foreigner tat to appear as regularly as possible.
The daily mail has never much bothered with the truth. The paper is more a vehicle to stir up anger and emotion (using the truth if it serves their purpose, if not, make it up).
There are a LOT of people who want to feel hatred towards other groups (psychologically apparently it's generally people with lower self esteem, it makes them feel better about themselves, as
at least they are 'not as bad as the scum they're reading about'). It can also help justify to some readers their feelings of racism, homophobia etc, which, with lots of society against such thoughts, they
want justified. These people are prepared to pay for such things - hence the daily mail.
It's a hate-rag basically. But without people willing to pay for it, it wouldn't exist! So who is to blame?
