I'm a Pureblood. (And proud of it!) My mom's a Squib. My dad's a Squib. My little sisters a Muggle-Born. My older brother is a Dursley. Most of my friends are Dursley. That is why i am such a Deatheater when i talk to them. I am weird.
Not all Slytherins are evil, nor all Hufflepuffs weak. There are caring, fiery Ravenclaws and twisted, cowardly Gryffindors. Your house is not who you are, it's what you value. Your house does not define you. You get to define yourself.
