Why are people so discriminative now a days?

I just dont understand. All my life I have grown up seing my borther and my mom and dad get discriminated. My brother is in wheelchair and he cant talk and has mental retardetion and before he went ont eh meshines people stared at hima dn said poor him. Ad when we were traing to find somewere to live the owners would tellus that they didnt accept people like that. Our old house we got trown out because the ownor said that he ate like a pig and that her floors were going to get dirt. I could not stand that. And the same thign whit my mom because she is also disabeled.

And my dad just got sent to jail because of nothing. they say because he got a ticket but they only gave him a warning notice. They do it because he is hispanic and they call him beaner and wet fish. You know I think people need to know that we are all the same and that we all need eachother. I mean have you seen the protest that are made because of the mexicans and how they want them ou of this country.! Why are people like that this days? Why cant we all be accepted as we all are?
