I'm sure this has been discussed before, but I'm looking at it in light of this article of TheJournal.ie.
Does the use of 'fag' or 'that's so gay' (gay as a negative adjective) bother you? Is it socially acceptable for straight people to use these phrases casually? Or should gay people use them?
It really bothers me when people -- especially straight people -- use them. My sister did it when she was home for Christmas ("these pictures are so gay") and I found it upsetting, if I'm honest. I spent the majority of my school-going days (from ages 11 to 17) getting called a fag, queer, bent, etc. on a daily basis and I'd be happy never to hear those words again.
