You’re kind of illustrating GP’s point. Throwing paint on a fashionista wearing fur poses very little risk- compare the risk to a Hell’s Angels biker who might literally kill you. And furs were always expensive which kept the quantity relatively low- compare the number of fur animals killed to the number that are killed for their hides to make car interiors, house furniture, clothing, and more.
If the fur protesters want to make a big impact they should protest leather, but you don’t see that. Instead they took their smaller symbolic victory because the meaningful fight is too hard and too risky.
