I don't think anyone should be banned for saying something dumb off the field, a fine will always do, anything else is just virtue-signalling. Say something dumb on the field = three games for straight red on the first offence. That's definitely enough. Just banning people for having bad opinions won't root bad opinions out.
That being said, an epic loss for them today. Hopefully they implode completely now. For us, one game at a time though. Each game starts at 0-0.
