I probably need a tin hat for what I'm about to post, but anyway, here goes:
So firstly I don't know the background to the Vinny J case, but mine is a general point as it seems pretty unanimous on here that we should be applying similar action.
Imo it's too much. I'd go for longer banning orders, public shaming, personal apologies, diversity courses and even community service, but whatever the circumstances, when we have downgraded so much other criminal behaviour that doesn't mean jail time, then jail for insults, however abhorrent they may be, is too much.
If however we're talking George Floyd or especially Stephen Lawrence type crimes then that's different of course and they should throw away the key, but shouting insults unless there is a catalogue of previous or a repeat offender, jail seems ott.
