I DO judge people. By their actions. I am with Chris_99 on not giving half a hoot about what you look like, what you believe, to whom you are attracted... it is what you do and how you treat others that counts.
I have been described as "too nice". But I like being friendly. I'd prefer to say I observe things rather than judge. I might notice someone has shoes I dont like but I dont think any less of them for it.
I never judge unless I know the person well. I agree that it doesn't matter is you're white,black,asian,gay,lesbian,straight,or bi. Were all humans and we share more things than we don't. I come from a strict family where if your anything but white, your not welcome and I'm so glad that I hadn't been influenced to think the same. One of my closest friends is gay and I love him dearly.
In person I am very nice to people. Everyone judges others but I try to give people the benefit of the doubt and consider that they might be going through something really awful. That is why it is a good idea to try to make the person at the check stand laugh, or say hello to someone you don't know. They might be in the verge of suicide and maybe all they need is someone to reach out to them. I fall short of all if this but I try to be nice most of the time.
We all judge.. ALL.. WHAT we judge about others just depends on our values... I am nice to all until given a reason; then, I'd rather dismiss than be mean, because meanness takes energy, which is wasted on someone I have no intention of engaging with, again. I spend time with people based on their integrity, morals, values.. Not religion, race, creed, sexual orientation, et al... But it's still a judgment...
