We are equal but different on several things, and we are unequal on a few things. There are very few qualities in the human being that are absolutely inconsequential. No two people are the exact same, thus they should not be treated the exact same.
Things that are equal but different:
-Gender, race (shouldn't matter, but right now it does), other natural attributes that DO make a difference in the way people view us. Men and women are different, so they deserve to be treated differently, but they are both equal.
Things that should be treated unequally:
-Disabilities, choices we make in life such as religion and weight (to an extent), etc. As far as the disabilities go, we should give them greater treatment but also prohibit them from doing things they obviously cannot do and maybe even some things they COULD do only with great difficulty. Choices are things we can control, so we should be responsible for them and not expect equal treatment. For most of these choices, there are privileges some choices deserve, and there are choices that should lose some opportunities.
Virtually inconsequential attributes:
-Hair color, eye color, things that only very obscure people would freak out over. There is no reason why a blonde should be able to drive and a brunette shouldn't...
Everyone should be allowed the basic rights of life, property, liberty and the pursuit of happiness, but anything beyond that is not a human right, thus up to debate and study to see who needs additional privileges and who doesn't. It's not a human right that we have a fire-station, but we have decided that it is for everyone's benefit to have such a station, and we also decided that nobody deserves its service more than anyone else. Driving is not a right: it's a privilege, and some people should not be allowed to drive.
