MY OPINION ABOUT...

"Barras bravas": personally i think that, all the people can support their favourite team, screaming, jumping, with flags, etc... but is unacceptable that this guys who come to the stadium drink alcohol, and later fight with the people of the another team and break all. i think that the idea of the football is play, and be happy

"Same sex marriage": Speaking for my self, the people of the same sex, that feel love, and are happy together, have every right to spend their lives together as any heterosexual couple, in my experience, the love is the first, not the sex.

"Child labor": i believe that during the infancy, all the kids just need play, smile, be happy, and the parents should be responsable with their childs, because bring a child into the world is very easy, but they need care, love, going to school, and primarily "be a kid".

"Killing stray dogs": what i mean is that all the dogs are living organisms, that they can feel, they can think, and are entitled to live, or when you see a little kid on the streets , do you think about killing him?, no, you think on found a house for him, well, the dogs are us little brothers

"Cloning": As far as I'm concerned the cloning is not bad, you just create another living organism with the same characteristics, another case is use that organism to remove the internal parts and thus cure the first, it was like have a child for his own good.
The new organism have the same right to live.
