Anyone else feel like there have been so many different ways the word "gay" has been used as a slur - both ironically and unironically - that the whole concept just kinda doesn't work anymore?
The only response my brain produces these days is just giggling and moving on. Like if your intentions are to shock me, I'm afraid that ship has sailed. Best thing I can compare it to is how poop jokes stop being funny when you hit a certain age, and start being a different kind of funny once you hit another.
But it probably really depends on your environment. Obviously if you do feel negatively about the whole, that's a completely valid stance to take. Don't think of this as me trying to ifluence what should and should not offend you.
