3.
An individual who has excessive sympathy for any group or individual that they perceive as underprivileged, and a lack of sympathy for any group or individual that they perceive as over-privileged.

They typically hold the view that the majority are responsible for any minority plight whatsoever, and that minorities can never, ever be responsible for their own condition. They often feel that the public is obligated to make special accommodations for every group, no matter how large or small it is. They claim to be against racism, but in actuality are racist against whites, and believe that modern generations are responsible for the wrongdoings of their ancestors. They will usually pursue useless degrees with their parents' money, and they will never be found studying the hard sciences.

A bleeding heart is NOT simply any left-leaning individual. Supporting social and environmental causes does NOT make one a bleeding heart. It refers specifically to those who take the views to a ridiculous extreme, make completely illogical, unrealistic demands, and are unable to recognize their own hypocrisy.
supporting gay rights = not bleeding heart

A word used by neocons to make fun of people who care about the environment, the sad state of public schools,the bullshit war in Iraq, or basically anything other than themselves.
More than 30,000 Iraqi civilians have died since the beginning of the war. Why shouldn't I be a bleeding heart?

6.
someone who is in a negative relationship. The person will not see it as negative, but they see that they are trying to help the person. In relaity, however, the 'bleeding heart' is being dragged down. This can end up in depression, suicicide or just feeling like shit. The bleeding heart will evernetually realize that by trying to help someone who didnt want help, they were really only hurting themselvs.you have to evalute what is more valuable in your life, and if she is worth fighting for, than fight. and if she is dragging you down, then get the fuck out of the relationship. That should be approched gently, you still want to be a shoulder for her to cry on, but you cant be emotionally invovled.
if your girlfriend has attempted suicide, has been put in the hospital, has been realesed is still a fucking mess, and ur still with her, than chances are, your a bleeding heart.
