The NFL receiver -- who joined the Donda staff earlier this year -- addressed the massive controversy surrounding Kanye following several antisemitic statements ... saying, "the world's reactionary and selective outrage at comments in the media made by my brother, Ye, have inflamed and sparked rampant conversation and reflection."

As companies like Adidas and Balenciaga cut ties with West, AB says the timing is not a coincidence.

"The people and brands that have relentlessly profited from Black ideas and Black culture chose to distance themselves at a very specific time: a time that demonstrated their prioritization of certain groups over others."

He added ... "None of us in this world are free of judgment, yet we live in a time where scrutiny and pessimism have driven our dialogues on cultural issues toward diatribes."

"Sensationalism and groupthink have forced people to not speak their minds and act out in fear rather than love. For these reasons, I stand by my dedication to freedom of speech, thought, and opinion."

Brown says he decided to speak out because he is against discrimination of any kind ... but makes it clear he's standing by Kanye's side.

"I remain true to the mission of Donda and our amazing staff and community," he says ... adding he believes Kanye's comments were taken "out of proportion" by the media.

"I remain committed to bringing new ideas, experiences, and designs to our world I remain in support of the humanity that is Ye."

The statement comes on the heels of sports superstars Aaron Donald and Jaylen Brown voicing their issues with Ye's comments ... which led them to leave Donda Sports.
