It is huge and you should celebrate it, but you don't have to be a cock about it because chances are you're just being instigative towards people who have no ill feelings towards you, and most likely some that are supportive. (And I'm not saying you, Afrocious, I mean the ambiguous you)
I went to a highschool that was 95% black and I remember the day after Obama got elected people were going nuts celebrating, which is great, but I also had a huge number of people coming up to me and taunting me like "YEA WE PRESIDENT NOW! WHAT NOW?!" and I wanted the dude to get elected too, so they're being assholes to people on their side for no reason.
I wouldn't take it personally.
It's like when folks hate on straight men. I completely understand why and move on.
If you are a white, heterosexual male in America, there's so much that will easily work in your favor, that when folks are given something good and necessary, it's possible pleasantries are thrown out the window. But again, it's not personal.
Also, let's not talk about this subject within this thread.
