If I ever had to give advice to some celebrity first dipping into social media it's that even if they're good with comebacks, you have nothing to gain by fucking with this respond to everything bullshit. You're the celebrity. Nobody gives a fuck about anything else, but they're going to see what you respond to and what you say. Also it's the Internet so more than half of everyone is a complete fucking idiot. Pick your strawman, someone out there is doing exactly that. Pick one or two of the things that make you look best, slam dunk those, and then turn off the computer and call it a day.
Prime example, Richard Roeper, who got dogpiled by beta cucks.
Slam dunked one, moved on.
Instead of getting articles about what a victim he was, he got articles about how based he is.
