The word 'gay' has very little meaning now. I wrote a blog about it.

You'll probably have to go back, it was an early one.
To be honest, I'm rather desnsitised by this point. I think most people are. The problem is, it still holds a lot of meaning to a good number of people, and so it is certainly something to be aware of. A lot of people operate under the notion that "I am (X) and it doesn't offend me so no (X) should be offended." And to be fair, it'd be a better world where nobody got offended at mere words.
However, if you've ever been roughed up for being different, you should know what it's like. It's worse when it's something more than just being fat or wearing glasses. When it comes to something where people have been routinely violated or killed, it leaves marks. Even marks on people who aren't necessarily offended by the words. I know. It's not fun being seriously hurt just because someone thought you looked "like a ******," without any corroborating evidence. People remember that, because it's not so old.
I've given up being offended. I moved on to pure mockery a long time ago, but it's not quite meaningless to everyone.
