Why are people becoming so sensitive?

[Jesse Google]

I hope everyone that has a tumblr, facebook, twitter, etc is noticing that you can barely say anything without everyone telling the original poster about how cruel they are. This is especially present in Canada, the US, and most of the UK. In Lebanon, where I am from, we have TV shows that make fun of homosexuals. Literally, all it is about is how homosexual men do things such as buying candles for "personal use". It's hilarious! BUT, if someone posts/writes/says something like, "women are usually more sensitive than men", then people (mostly women) begin to talk about how it's "stupid, sexist people like you that are ruining the world". Why can't any one accept facts, or even take a joke anymore?
