Addition to this thread of thought:
http://matrixmann.livejournal.com/149618.html It needs to be expressed as evilly as the circumstance is in fact: On one hand, it gets condemned if far right activists drag their kids to their rallies and make them scream hatespeech paroles that they fail to understand, but on another hand it is attributed to be "good" if social-democrat leftist activists drag their entourage to their rallies and it is considered to be "well for the development of children's moral and their understanding of values". Even though you can guess, they fail to understand these paroles as well because of their age.
On another note to the subject - everyone who has a basic instinct of empathy knows you never use violence in front of kids. It's like a natural law that the majority of people gets it is extremely harmful for them to be victim, involved or witness to it.
As much as mankind is an animal species that tends to be egoistic and sneaky if only an action brings them closer to a goal they want to achieve, you will know you can also abuse this circumstance.
That's also why you don't carry children to rallies.
Fight for your own crap, but don't use your children as a protective shield!
You're as shameful as somebody who uses children for his personal amusement.
