I think part of our different view might be based on how our electoral system is.
So to explain: Trump's never won a popular election before. Even when he became president, most Americans voted for his opposition Hillary Clinton. We have a very gerrymandered and corrupt voting system to oversimplify. Because of that The main decider for presidential elections is voting turnout. If a lot of people come out to vote, the Democrats usually win. If they don't the Republicans win. Voter turnout is higher when people want to vote for the Democratic nominee. No one really wants to vote for Biden. Most of us will vote against Trump myself included. That being said, if we run a very unlikable candidate against him like we did in 2016, he might win and that's terrifying. This election is serious so we should take it seriously and run somebody likeable and not half way to being a turnip.
God forbid if Biden stays in there, I hope he wins. I'll even vote for him but I am not feeling good about his odds.
