The issue is these young "progressives" seem intent to cut off their nose to spite their face. In 2016, many threw a tantrum that Bernie wasn't nominated and either stayed home or voted for Trump, and now they are the same ones protesting abortion bans, LGBTQ+ rights, and climate change which are a result of the Trump presidency.
No one I know IRL did this. My parents voted for Hillary (originally planned on Stein as a protest since SC is safe R but they were turned off by her anti-vax BS) and voted for Biden despite being big Bernie people and farther left than me (my mom has a subscription to the Freedom Socialist newspaper FFS)
