I can't see the example of brutal / rude feedback here. But I have two assumptions based on the thread:
your colleague might leave feedback by bringing personal and racial issues
your colleague leave too much feedback that trying to scale you up but without a proper diction
If you are experiencing no. 1 it's no the other way around to stay patient and find another place that might have a better environment with clear policy. Wait until you sure that your new place is your new comfortable home.
If you are experiencing no.2 please discuss with him that you can't follow up his feedback because it's too intense and overwhelming. Or if you find some his/her feedback are not worth to read. Just skip that part and give your best value to him. Skipping unnecessary feedback on PR review is not a sin.
Whether you are experiencing no. 1 or no. 2 you have to communicate it to your manager (team lead, engineering manager, HR, etc.)
I feel that you are experiencing toxic culture. It's might be exists everywhere. You are just need to aware of this situation and find right and trusted colleague to share your bad experience and finally cope that issue.
As an additional, you can tell your HR. Your mental health is also matter. You are precious than rude feedback from your colleague.
