Antonio Brown is going way too far with his most recent Twitter antics ... sharing an insensitive image making fun of mental disability on Monday -- and people are pissed.
AB has had zero filter on social media lately ... firing tweets with seemingly no care about the repercussions, including tasteless jokes about Tom Brady's marriage issues with Gisele Bündchen.
34-year-old Brown randomly decided to post the offensive picture just minutes ago ... showing a distorted image of the Arizona Cardinals logo and a modification of the team name that featured the R-word.
"Starting my own Team Sign 🆙" AB said in the tweet.
Antonio Brown Backs Kanye West Amid 'White Lives Matter' Controversy
Of course, not many are laughing at his awful attempt at humor ... and made sure to let him know in the replies.
In fact, some users are even comparing AB's actions to Kanye West, who was recently criticized for preaching "White Lives Matter" over the past week -- leading Brown to add, "All Lives Matter" in a post of his own.
"are you and kanye in some kinda competition?" the user said of the newest post ... while another pleaded, "you gotta just get off social media bro."
AB hasn't deleted the post yet ... and given the way he's been handling his online presence lately, it's doubtful he will.
