As shitty as it is, this country 1. Isn't designed in such a way that would allow a third-party candidate a genuine chance of winning and 2. Has too many centrists that will vote for Biden regardless. Trump has repeatedly garnered heavy support in Republican polls, so they're pretty much almost all in on him. Splitting the blue vote between Biden and whoever else will only lead to a Trump victory after which we might not even be ABLE to vote in 2028.
I'm legitimately having a panic attack. These airheaded anarcho-kiddies are genuinely going to land us all in camps.
biden's doing literally nothing to stop states from criminalizing lgbt people's existence 
their fears about a trump presidency are valid but i wish these libs would stop putting their hopes in the DNC when its clear they have zero interest in running a candidate that isn't complete dogshit
Over half of Reddit is American, with English and Candians being the next to largest groups at about 10% each. Unless you are in a country specific sub, or a hibby sub for something not common in the us, chances are that you are talking to an American.
According to reddit's own statistics, 40% of Reddit users total are from the US, and 49% of active daily users.
Your odds are about 50/50 US to rest-of-world.
So it's a safe assumption that the oerson you are talking to on Reddit is an American is what you are saying
If you consider more likely wrong than right to be a safe assumption then sure.
