This is an American thing. Everybody is SO concerned about appearing politically correct, they'll jump on anyone who dares upset the masses. Unfortuneately, social media influences many, and there's a lot of frightened little sheep who're terrified of being vilified by strangers. I despise people who play "follow the leader," and usually troll the hell out of anyone who jumps on one of these bandwagons.
Roseanne is a comedian. She's ALWAYS said controversial things. But that's what comics do! At least, they used to...until everyone became too afraid to offend ANYONE. Can you imagine Blazing Saddles being released these days?! God, no. People would shit themselves...and begin a campaign to destroy whoever was involved with the film. Actually, no. That film would never be greenlit in the first place.
When I first heard about Roseanne's tweet, I KNEW she was history. Did I think it was racist? Nope. Funny? Oh yes. Advisable? God, no. But like I said before, she's KNOWN for pissing people off. She's been out of the public eye for so long, many people either didn't know or forgot.
Ten or twenty years ago, she might've been reprimanded. There definitely wouldn't have been such a big deal made over this. Sure, the NAACP and Jesse Jackson might've complained, but that's no surprise.
Political correctness is KILLING this world. Mind you, I've never been a fan of Roseanne. She's crass, loud, trashy, and has NO class, whatsoever. I never liked her stand up routines, nor did I watch her show when it first came out. But...I absolutely do NOT agree with the show being cancelled over a tweet. Think of all the writers (and cast members) who suddenly don't have a job. Over this bullshit.
Liberals have found a way around the First Amendment...if someone says something you don't like, call it racist or hate speech.
