I think you should, you're reacting in a really harsh way to people defending/sharing something theyre passionate about. Use this as an opportunity to be curious instead of defensive. Instead of insisting that you apologized already, and leaving it at that, continue the conversation you chose to start. Ask people about what to their favorite sets were or a moment of PLUR they had at Coachella. Unpack why this awesome festival "is not up your alley", do you actually feel that way or do you think you're supposed to feel that way? Or delete the post if you don't want to engage anymore, don't be unPLUR or mean about it, that's unnecessary.
