Can someone please explain why this election season is so bad?

I (17y f) am not eligible to vote. However I just had a recommendation post on my feed with someone scratching a car to get a Trump sticker off. I don’t know my political party but I do have basic manners and respect. However, it was a progressive place and I went there to get educated and said it was a bad election season and they went full out. I even stopped interacting because they’re confusing. So if someone can please explain as to why we like Trump or Kamala I’d be happy to learn. I wanna keep an open mind for future elections considering I’m missing this one. Usually I do not worry about politics because I cant vote so theres no need. I did research on Trump and Obama and Joe. Joe was a sad case for me. I only found good things about Trump though that are actually true because it goes back to the 1980’s and 90’s.
