You claimed South Africa as giving "virtue-signalling gestures" claiming they have "They have little to no impact on the conflict" and said it was stirring up hate when in fact it was speaking out against oppression.
International pressure, sanctions, boycotting and diplomacy helped to end apartheid in South Africa.
Pressure from all sides. Gestures like the South African vote count as speaking out against oppression, and put pressure on governments. They gather momentum and gain publicity. Other governments follow suit. It all helps. It may be symbolic but symbolic gestures add up and build to change situations.
Of course, if you support Israeli govt you'd prefer us all to look away and ignore it. That helps nobody except those who continue their oppression.
