I get more offended by people who are too easily offended.
To that point, 'gay' is a word I find that is used to voice frustration. As long as there is no real malice behind it, I think nothing of it. That said, I am far more scathing of people who take the white knight act and take shots at people who used the word harmlessly, or take it as a sign that they are somehow higher on the social scale of things.
In the end, it matters on what the context is.
But used in the sense that "This OP bullshit is so gay", "Doing the dishes is gay", etc, means nothing to me. If all our speech had to adhere perfectly to political correctness, our vocabulary would be much more boring.
