How do you think an unarmed mob of people can fight the most militarised nation on earth? There are nations like Egypt with more corruption and repression than the US that have successfully prevented any kind of insurrection due to its strong military.
In the US, the police, military and other armed forces (ICE) all mainly consist of literal nazi’s. I think you don’t realise how bad things will get if the liberal opposition keeps making the bad choices that have made them as weak as they are now.
Don’t blind yourself with the idea that the US is somehow different than all other nations with oppressive regimes. There is a real possibility that the US moves further and further into fascism and not taking that risk seriously will ensure it becoming a reality.
