In a sense it is not, but the decay of our society sure makes being kind and loving feel like weakness. Obviously there are acts of kindness we feel good about such as giving money to the homeless, but doing nice things for people just as an act of friendship seems to make you feel like a bitch these days. It is because people are so stupid and often times, an acto f kindness won't be repaid and you'll feel like a bitch for not hardening yourself to other people.

At an end of the spectrum. Getting walked all over is just as bad as being a prick all the time.
