I must disagree.
We need not wait for marginalized groups to be impacted to decry T1 ISP censorship. Ban whatever speech you want; the method of enforcement should be to arrest the perpetrators - not stop the sale of paper, the delivery of mail, or blocklist class A ip ranges.
On a more philosophical level, this is the question of “kindergarten policy” - do we punish those who crayon on the walls, or do we take away everybody’s crayons. To punish the ability to do wrong, or the act of doing wrong. Like most philosophical questions, there’s no good answer to this.
