Life could be better if people stopped to think about...

Some subjects are still taboo and the motive of prejudice in our society, and honestly do not understand why.
For example homosexuality
Each one is how he is, in what they annoy heterosexuals?! They have the same right as us to be happy and have a normal life without having to hide from people filled with prejudice. They have the same needs as us, the same dreams and desires as we do. So they're not so different. As I see it is not a crime or immoral. 
For example spiritualism
How can people believe in God and not in spiritualism. They say this is bullshit and never saw such a thing so don't believe. But have you ever seen God? That I know they only believe in God from what they hear, and they believe in his existence, so why not believe in spiritualism when they hear about it. Have you ever found something contradictory to what was said on this subject? I don't but well about God. They say that God is just, but where's the justice when children five years old die of lucemia?! Children who don't even know what's right or wrong. Don't tell me it's to punish the parents because there were other ways to do so. Where is the justice in accidents where the victims are women at the point of giving birth?! Where is the justice when people with a good background living on the streets with nothing to eat, and people with no respect and pretentious to live in luxury?!
For example people stronger, not obese but lets say stronger than what people consider normal.
These people didn't choose to be like that. Sometimes it's genetic, or a consequence of disease, etc.. It will therefore be a cause for enjoyment?! They are people like us, with feelings. It could be any one of us.
I think people should spend more time thinking about these things in life, they should look to themselves, should extend a helping hand instead of enjoying and humiliate.
Did anyone realizes that something is wrong?!
I personally am not homosexual but I respect and I have friends who are. Is not that why they are less than me!
I personally don't know if I believe in God because I think this world is not really fair. I believe in spiritualism but from experience.
I personally can not stand when people speak ills or laugh with people stronger or less beautiful. I have friends and they are all different, but I like them for who they are. And don't consider myself perfect or close to it, to find me the right to judge or make fun of anyone. Because these people must feel terrible when such things happen! We should not do to others what we don't want to do to us! But few people think of it all and apply that phrase. That's why our society is how she is. Because many don't like when others do it to them but they do it to others!
It's sad but I'm ashamed of the attitude of certain people. And especially sorry for them because in the fund they must be very insecure or unhappy to be how they are!
