AFAIK she hasn't killed anyone, and I have no idea even which flavour of "Leftism" she favours. If its some flavour of sincerely-practised left-Anarchism she gets a full pass from me.
"Rightism" killed tens of millions of innocents last century.
Murderous Statists are murderous, whether they kill for "The People", for God, or for Mammon.
Going on a tirade against "Leftism" in somebody else's thread is indecorous, yes.
Its also pointless, hypocritical and divisive.
